Autocal is obviously the best choice. 500+ for it with the tune though... Well worth it if you ask me!

There is no substitution to a good pcm/tcm tune done by Justin...the man is a tuning guru. Your next step should be a tune, then if you are left wanting more start laying out a modification plan...I have built up my tahoe step by step and am now approaching my final goal...forced induction.
