First off i would like to say I am very VERY pleased with my 1st and 2nd tune from you. My question is it what can i expect from an LQ9 swap with a cam and springs? I plan on reusing my longtubes, and cai. I do drive this truck everyday and tow with it occasionally so i'm not hunting a max effort engine, Right now my 5.3 is all stock with the exception of the mentioned bolt ons and your tune. Trans is completely built with the beast sunshell and vette servos. Rear is 4.10 with detroit. 2005 ECSB 4x4 with 33's.
