Dyno shows peak torque at 5800. Yes I have run the car in both the quarter-mile and 1/8 mile. 6.63 @ 104 with a weak 1.52 60 foot. I appreciate the comparison with your set up, however, I am dealing with a very soft launch. My car leaves like a Yugo with a misfire. I attribute it to converter as well as a 1200 RPM drop on shifts. I’ve already tried everything else and everything continues to point to the converter.
