08 CC 5.3V-8 20" rims...........When getting on the freeway or taking off above half throttle it feels like its clogged up then it just goes, truck has 8250 miles on it. Anybody else get this feeling from there truck?

sounds like throttle delay caused by the throttle-by-wire design and torque management. if so, it's normal and the intention of GM.

sounds normal to me. you really want that to go away, get a custom tune by justin at blackbear. do some research on it in the vendor section or go to his link to the left.

besides messing with the computer will anything else help? Air intake, exhaust.......?

 

 

nope, not if it's what i described above. you can bolt on anything you want to make more power and it will still be tamed by the ECU.
