That driveshaft RPM is ugly at the hit really. It LOOKS like it unloading but without seeing the G force with it hard to confirm. That DS RPM line is pretty jumpy down track so could just be an issue with the pick up. Is it a 2,4 or 8 magnet pickup? The G meter will tell a lot more of the story with that info. See if it is more linear and not as "jumpy". If it is then those "waves" in the DS RPM could just be a sensor issue.

That RPM drop is killing ET for sure. Also the RPM line shows the car slowing at the hit. Dragging the engine RPM way down after the initial hit. Likely also a converter thing. Get that line more linear without the drop and straighten that DS rpm line out and you will find a fair amount of ET...

One other thing I didn't mention earlier in reference to the fuel pressure. I would want to confirm the reading on a gauge as well. Sometimes racepak sensors can be not so happy. With fuel pressure that low I'd want to make sure
