In the next month or two I will be buying my parents’ 2012 GMC Duramax, completely stock. They purchased it with 6400 miles and it currently has right at 57k miles. I would like to add a tuner without dropping a bunch of money removing/deleting parts. It will be used as a daily driver (around 50 miles round trip per day). I’d like to maximize mpg mostly.
So what’s the least intrusive upgrades I can do without dropping several $k’s doing a full blown delete?
Recommendations? Of things to replace as soon as I buy it?
Thanks in advance!
