I know theres a dedicated thread to tuning but i got 39 reviews with no reply and i got help on this thread before so...2001 GMC Sierra C3 K&N CAI have had the Superchips Flashpaq for about 2 years and i just updated it via their website so hopefully i can get more out of it but as far as shift pressure and shift points i want to get the most out of it i can till i get my exhaust then get a custome tune....Anyone have any advice with the hand helds besides i know i need to ditch it and get a custome tune

 

nope that is all that it does and leave it on superchip value its the best as far as shift pressures goes.

 

No cross posting please.
