Not sure what racepak is showing but the shift points are all over the place that might be what is giving you goofy ET's.---you have a fairly heavy car with a low HP engine and once you run out of gear going into high gear it just does not have enough power to recover and produce a real good ET.----Not being overly critical but the driver must aim for consistent shift points ---are your RPM shift points in the correct range not too high or not too low???---what is your finish line RPM it seems to be fairly low shouldn't it be in a higher range looks like low 6200-6300 range???--just my observations from the video----FED 387

I lowered the launch rpm to 5800-6100, 6500 would be typical, we're just trying stuff. Optimum shift point will probabbly be between 7000-7100, shift light is at 6500 because I know she won't hit every shift. Not sure about the goofy ET comment, we made 3 runs without changing the launch rpm and the cars ET varied .017 and the 60's varied .011 WITH us changing other stuff on the car. Yes, she isn't hitting the shifts perfectly but I would also like to point out she is also NOT shifting clutchless per se. Correct, the car is not pulling in high gear and we have to work on the setup for that.
