Re: Duramax/hypertech mileage
Thanks for the update.
Did this come off thedieselplace.com?
I have been reading some of the diesel forums and everyone there is out for hp and torque, not fuel mileage.
I live about 800 miles north of Edmonton Alberta and make about 4-6 trips a year, mainly empty. I love the 310 hp and 590 lb/ft when pulling, but I would love to be able to detune the power for mileage when running down the highway empty with the cruise set at 70 mph.
So for $150 he will send me a new computer with programming I want.
I think I will email him.
