Got it on the dyno and ran out of fuel pressure the first pull :doh: It made 485whp the very first pull with no timing and he stopped until we fixed it. Have a Magnafuel rising rate regulator to put on this weekend and try to get enough pressure from the stock fuel lines on pump E to make 600-700whp. This winter I'll hopefully get a fancy hanger so I can put a second 525 pump in it and do -10 feed and -8 return the whole length of the car.
