I have tuning for mostly stock gas trucks, I just don't have the time to work on tunes for guys with cams, rockers, ect, ect that are looking to get maximum performance. But if you are looking to get better mileage, some added power, and alot more pep out of a fairly stock truck I have a tune for it. You can PM DJMS if you want an unbiased opinion on my gas tunes - I think just about every friend and family member he has with a GM gas truck is now running my tuning.
