No fuel pressure switch, and yes it is the same pump as the motor.

Makes sense to me. I think this will work to test if this is truly the problem. Hold the purge open until the nitrous hits, if the car goes then sweet I just need to move the nitrous line. If it still bogs, then time to continue chasing the problem.

kindaslo,
Just curious, I have a simular set-up and wanted to know what your times are on the motor. My best is a 12.4 @ 110mph on a crappy Hawaii track, but that time seems alittle slow to me.

Thanks
Brian
