Whats The Best Power Programmer For My 07 Sierra 5.3

I got zero MPG gains with the Edge. Then again, I got zero MPG gains with my Nelson tune too. My right foot and the smile on my face probably have alot to do with it too.

With no muscles, being a skeleton and all, how can you have a "heavy foot"?

Black Bear Performance Tune is the best for any GM truck.

What do you guys think the best programmer is? I think im debating between superchips or edge...

For the money you are way better to get a custom tune. Everyone is going with blackbear tunes and love their trucks afterwards. I have Edge right now I like the guages but I only used economy mode and I don't think it helps much. Diablo is a much better tuner but no TCM support. Seriously look at Blackbearperformance.com it cheaper and better than a programmer.

TCM?? what did you mean?
