Default F250 6.7 engine lag?

I have a 2016 with about 9k miles on it right now.
I have noticed on a slow roll or under 10mph trying to get out into merging traffic, that it hesitates badly when you hit the pedal hard. To the point that it is almost dangerous.
Is this engine lag or the 6 speed transmission trying to down shift?

On my 2004 Dodge 5.9, it would pin you in the seat when you hit the go pedal hard. It was a 4 speed though. It also would spin the tires on take off from a stop if I was not careful.

Can I get other 6.7/auto users feedback?

That's normal. Try driving a new Dodge or Chevy, its way worse than the Ford. Had both a Chevy and Dodge diesels for work trucks.

I have a'12 F-250, I have gotten used to the lag. Just need to hit the accelerator about a half second before you actually need to go.

If you're driving with both feet and have any contact with the brake pedal they will lag. At least mine will.

Pop the hood and make sure all the boots and connection points on the hoses from the heat exchanger (intercooler) are still good. My buddy has a 15 and he had this issue. He said there was some soot covering the engine.

It's turbo lag. Normal but can be frustrating.
As said above anticipate it and start sooner. Putting it in
Tow/Haul seems to help accelerate quicker.

Default F250 6.7 engine lag?

I've read a few good reviews about these types of things-
http://www.stage3motorsports.com/105...y-Booster.html

My 5.9 dodge in stock trim dang near got me killed a few times because of its turbo lag.
My 6.7 ford in tow tune does great, stock tune not so much.

I also run in tow haul mode when in traffic or in town to keep the engine RPMs up in the right gear. One of the downfalls of the 3.31 gears I guess.

Could be your traction control taking over.
Turn the traction control off and hit it.
My 16 will light up the rear tires when you punch it with traction control off.

Another thing this Ford newbie has noticed:
When the tow/haul is on, it really assists on engine braking. But I have tried the engine exhaust brake before and have not really noticed anything. Can you really feel or hear it?
I am only towing about a little under 5k lbs now. I haven't hooked my TT up to it yet.

Going off memory from when I read about them before- they are a pedal position multiplier of sorts. They fool or tell the computer that you mashed down the pedal a lot further than you really did.
That's my understanding of them anyways.

I also remember a reviewer stating the warranty would remain intact since it didn't change the stock tuning or engine performance.

Regarding the exhaust brake, Absolutely! I've only used it when I've towed heavy or when driving mountain roads. It works best when you use the manual up/downshift on your trans selector. I was towing 10k lbs down a very steep dirt/rock mountain road I Colorado and was amazed I didn't even have to hit the brakes!

Just select a lower gear and push the exhaust break button?
I would assume you would also need to also be in the tow/haul mode.

I dont remember if you have to be in tow/haul or not. If you have a FX4, the hill decent feature is great too.

I thought that the new L5P Duramax had the best throttle response when I was comparing it and the new Ford a couple of months ago. I didn't test drive a Dodge so no help there. The '15 Duramax I had would hesitate when you mashed on it much like you described.

I don't know about all that. I had a '15 Duramax and an '15 Cummins, and my personal truck was a '12 Powerstroke. I noticed driving the Duramax and Cummins, I had to punch it earlier than I did my truck to pass.

I mean, Its really first world problems, but just my experience.

I wasn't arguing that the LML had or didn't have lag. I was just giving my experience that my L5P has a much better response when I punch it than my LML had.

It's not turbo lag, its torque management. All of them have it. Can't slam the transmission with 900+ torque so they manage it through software.

The throttle boosters help but still don't take it all away.

Torque management doesn't make it feel like it's not going to go.
If you only feel it at dead stops or very slow speeds I would bet money it's your traction control.

Yes it does, that's exactly what it does. Most of the modern diesels don't even get full torque until 3rd gear. Traction control will only take over if you break the tires loose.

I know exactly how it works.And no it doesn't
I have the same truck as the op and I know mine doesn't hesitate like that unless it's trying to go but fixing to spin the tires.
I keep my psi in the rear tires around 45-50. If I put it any higher than that they will spin easily when punched.
Our trucks have 65 more h.p. than yours, so they will easily break the tires loose.

So what do you believe torque management does?

Too bad that Ford doesn't put all that claimed power to the ground efficiently.

Oh good Lord!
I could find link after link showing the Ford with better times, but it's not worth wasting my time.
The op is wondering why his truck seems to hesitate or lag at slow speeds. I am not sure how Ike Gauntlet or some other test times has anything to do with that.

Once again...I have the same truck as the op, and mine does not do that.

You are probably correct. I was making that point in response to your statement about having 65 more HP than the Ram. Well that's all fine and good. It if it doesn't gain you any significant margin other than maybe in a drag race who cares.

And you didn't answer my question about what you believe torque management does.

Me. That's why I went with the Ford.
Ike Gauntlet tests or others like it have very little to do with the way I or most others will use their truck.
I or most folks will never pull a maximum load up a mountain...
There was a test done not too long ago where they were pulling fifth wheel campers. That is more in line with what most folks are using their trucks for.
I wonder who won that?

Torque management limits the power to help save your drivetrain.
However, it doesn't make your truck fall on its face.

Agreed about the max load up a steep mountain won't apply to most folks but it does keep everything on a level playing field for comparison.

I know which one you are talking about towing the 5th wheels campers but that was done before Chevy and Ram upped their power numbers.

I won't argue too much on the point about most people using their truck how it was intended. Some people like to **** away money to say look at me, I drive a Powerstroke, Duramax, Cummins. I also believe that why a lot of those folks have emissions troubles.

As to the torque management issue, you can't even admit when you are wrong. If the torque management limits power as you admit, then it definitely can cause the truck to fall on its face when you jam the throttle. That's exactly what it's designed to do to help save the power train.

Ive driven all of the diesels except the 2017 Chevy. They all have hesitation when you punch the accelerator quickly whether it's from a dead stop or going on-off-in the throttle.

Does this motor have a dual stage or compound turbo on it?
If so it could be a problem with the first stage causing the lag.
Turbo lag should not be this pronounced as long as the fuel flow is correct.
Torque management is a whole different thing as it retards timing on gas engines and reduces fuel flow on diesel engines to protect the tranny from shifting too hard and breaking something. Been many a souped up hot shot rig knock out the rear end and/or tranny from too much torque applied during shifting under heavy load.
An after market tuner might help if the lag is just the nature of the beast.

RPM..... RPM... RPM.... that turbo needs exhaust gas to work... 5th and 6th gears are overdrives... if you need mind boggling acceleration, push that little button on the end of the gearshift; but do it before you plan on needing it... and it you really want response, lock out 5th & 6th around town..

Exhaust brake button is useless 95% of the time in Texas... even towing 12.5K it takes high RMP to work... but it does work going down the 10% grade into Palo Duro canyon... yep it do....


Oh.... 3:31 gears and bigass tall tires ain't about acceleration.... get you some 3:73's or 4:11's...

If it's a stock truck it has a single VG turbo.

What you are talking about is defueling between shift which I suppose could be part of the torque management strategy.

Lol! What am I wrong about?
Did you bother to read the op's post?
He said that his lag was so bad that it was dangerous.
That is one statement I have never heard from anyone driving a 6.7 powerstroke.
I can't remember but I think my truck will do 0-60 in less than 8 seconds.
I would hardly think that someone merging in traffic would find that dangerous.

Yes I did read it. I was wondering if you did.

Things like this are subjective. If you are used to driving a vehicle that has instant throttle response then the new diesels are gonna disappoint you. All of them have a degree of delay when mashing the throttle.

I have the BD throttle booster on my Ram and I run it in the 75% setting and it makes a huge difference. There is still a noticeable delay if you are cruising, let off the throttle and get back on it quickly. It's probably in reality 2 seconds or less but it's noticeable.

The only time I've run mine 0-60 I had 500# of feed in the back and it ran 8.1.

I am glad someone else has or admits about this problem.

I had a 2004 Dodge 5.9 before this one. It did have an Edge Juice controller on it, but it always stayed in tow/haul mode.
It would out excellerate my friends F150 from a take off and I never had a problem shooting out into traffic. My 6.7 does haul better though.
I guess just different beasts?

My 2015 Cummins does that too, lags when you gas it.

Things like this are subjective. If you are used to driving a vehicle that has instant throttle response then the new diesels are gonna disappoint you. All of them have a degree of delay when mashing the throttle.

I have the BD throttle booster on my Ram and I run it in the 75% setting and it makes a huge difference. There is still a noticeable delay if you are cruising, let off the throttle and get back on it quickly. It's probably in reality 2 seconds or less but it's noticeable.

The only time I've run mine 0-60 I had 500# of feed in the back and it ran 8.1.

There is no doubt torque management keeps you from having 100% of power available, but I have never been in any situation where I have punched the throttle and thought I may be in danger because it was falling on its face.
I have punched the throttle and felt traction control take over because of rear wheel spin.

Is your standard or auto, what year is it, and is it all factory?
Just curious on these things on different people's feedback.

Then yours and mine drive totally different on initial acceleration.

I would have it looked at.
I live in the Conroe area, but do a lot of work around Houston. If you are ever in the area and would like to take a ride in mine to compare, let me know.

No use having it looked at, it's how these trucks run. I have a stock 2015, it's the best towing truck I have ever driven but you try to hot rod it and you will be disappointed!

The 2015+ 6.7 have VGT turbos, changing the tune can change how the turbo spools up. Since the turbo has the ability to change the pitch of the vanes to accommodate for different boost needs.

Well if the VGT is not working properly or at all at low rpm/load and closing off the outlet then the aspect ratio is too large to get the necessary flow velocity and the turbo won't spool up. Can also work against you going the other way as well. If the VGT is not opening the nozzle to increase the aspect ratio of the turbo outlet it will kill top end power.
There could be some issue with an EGR valve sensor or the PCM may just need a reflash. Either way a diagnostics might find the problem.

I think a 2 stage or compound turbo is a better setup but costs a lot more and probably make EPA people have seizures.

Forgot to add the EGR send data to the computer which in turn controls the VGT opening and closing. On a gas engine the o2 sensors provide the data to the computer to adjust the duty cycle of the injectors.

Im new to diesels. I own a 2015 and 2016 F250 6.7. Both run like demons...or sting like a "Scorpion"...apparently name given to engine. I dont like too or mean too but sometimes hotrod and dont notice any lag whatsoever in either truck. Both were purchased aftermarket at auto auction and both came from oilfield fleet.

Both pull my trailers like a charm. I was really surprised my first time driving in mountain snow over Monarch Pass in CO...without a load...setting exhaust brake and trailer mode wihout cruise control how the motor set itself when tapping on the brake at desired speed and it stayed there on the down grade.

OP...I hope you get a diagnostics run. I think its your programming.

I say its normal in the newer trucks.
I have a 12 model power stroke deleted with sct tuner.
I have 07 classic duramax with super chip programmer.

From slow roll to stomping it to floor. The d max will spank the power stroke on response out of the hole all day long. Its a lil aggrevating. Kinda just feels like it takes too long for ford to get going. But when she goes. She goes.
