hey has anyone here used a hypertech in-line power tunner? I have an 05 my buddy had one on his 04 he loved it . any more info thanks
You can get custom towing tunes. Personally I do not like running any tune if I pull over 10K, I did once and my truck kept heating up. Put it back to stock and it was happy.It seems everyone likes the SCT with custom tunes for performance but how does it do towing say 10-15,000lbs in 5-9% grades, I dont see to many people doing that with anything other than stock?
