First off, thanks for having such a badass site. I have a bone stock 2005 2WD Tahoe, which is desperately in need of some modifications. What would you guys recommend to start off with (intake, headers, tuner, etc.). Also, what brands have you guys found to be the best. With a million out there, I want to buy the best the first time.

Looking to get some new life out of the engine, and then plan on lowering it next.
