Blowing shit up with HP TUNERS.


What's up fellas, checking in. I have an 03 Sierra rcsb 4.8 5 speed all wheel drive and a '12 cts wagon 3.0 AWD. Had to buy the wagon because the manual transmission in my hot rod decided to leave the chat earlier than expected SO now im here. Broken truck, dick in hand, and plenty of time to browse the interwebs so lets get it on!


Serious note, I've been spending alot of time on the 3.0 tune in this Wagon so I'll post up results when I have them, thanks in advance for all the super great nuggets of wisdom to follow.....
