this tune is for my dads Service truck. its completely stock, he would like a little more power and fuel mileage. I'm still learning on tuning any help is greatly appreciated
oringal tune out of truck.hpt
new tune for truck.hpt
the original tune is the one i pulled out of the truck and the new one is a tune i compared to 6.0 ss tune. But with the new tune when you hit a hill it uses power and drops speed.
The truck weights around 12,000 lbs.
