As the converter tried to couple that's when the boost shot up but the power didn't climb.

The only explanations given that information are:

1. The operator does not know how to use the dyno.

2. The operator did not care that he was recording decel time over the top of the accel run.

excited for the new PTC and actually put the power to the ground

ptc makes a nice converter

It was a high end converter spec'd for 500rwhp, the new set up just makes to much torque for how loose the converter is. Not blaming the manufacturer just the progress of my build.
