Tuned PCM On A 07 Tahoe/Silverado Anybody?

[Haulin' T&A]

Just wondering if anyone has done it yet and what kinda gains were noticed. Does the Active Fuel Management stuff have any sort of negative/positive affect with a PCM tune?

I saw a result on a '07 Avalanche on pt.net and stock was 217rwhp and tuned was 250 rwhp through a simple mailorder through Nelson. He said he didn't spend much time on it b/c the owner wanted to do a cam/heads/turbo on it so he just mail tuned it this time. Not bad results.

I haven't tuned one yet, but I'd like to! My neighbor has a 2007 NBS Suburban, maybe I can convince him to let me tune it for him.
