Your electric water pump, gaskets, springs, injectors and Ramair......all these things may raise your HP, but did they raise where it PEAKS? Your exhaust MIGHT have, but not by 900 rpms. I see a cam flattening out the curves, but raising the peaks again? No way to tell or guess. You need a dyno.
I wouldn't shift at 6100. Not when you're paying for a custom burn that may be wrong.
If my engine was stock i could see what your saying. But since it'* not, no i am not out of my powerband
So what IS your powerband? I'm trying to save you from some grief. You're the second person with a 95 to have the same idea here......with GMtuners, and without Dyno data. Don't make a mistake with this one. Do it right, or mellow out that shift point.
