I just got back from carlisle, and while I was there, I had my car dynoed. I had previously had it dynoed in stock form at 305/315 hp/tq. After a few minor mods, one of them being a Hypertech programmer, I figured I'd pick up a few ponies.....wrong. I dynoed at 295/305. The technitian said my hypertech was #1 adding too much timing up top, and I was detonating #2 was making it run too rich....around 11.5:1. I was at a perfect 14.3 until he hit it, then it dropped into the 11s and stayed there all the way to 6300.
I am immediately removing the hypertech programming from my computer.
