Was working on finding out why we break up and backfire at WOT. Taped our FP gauge to the windshield to see if it maintained 55psi. Seemed low at idle, so being former NASA scientists we increased to 65psi. Really bad idea. 3/4 of the way down the 1/8th it shut off, came back on, then quit completly. We can get it to run but we have to increase rpm to say 2000 and it sounds like hell. What damage to you think we caused?
