Those Vettes could weight less then your SRT-6. We have a corner weight and dyno day coming up and the Vettes went in a few weeks early and the heaviest was 32xx with the driver. Less drag, less weight, more power, 315's or bigger in the back with a posi. Not a surprise. The shock is that you could hang as close as you did. So congratulations, and the tune must be doing something. (or I've been drinking)
