Low fuel pressure at high RPM
Steve Kahn was here on the weekend to tune my car. We managed to get more done this time than before until we ran into another problem. It seems that my fuel pressure is dropping at high RPM. We were doing 3rd gear pulls at about 10psi and at about 6000RPM the fuel pressure would drop sharply and I would lean out.
Steve upped the duty cycle on the injectors to compensate, but I'll have to fix this before he comes back again, possible in Sept.
Steve recommended changing my fuel filter to start, but I'm also suspecting my FPR, just because I don't know what kind it is, if its working properly or if is even installed properly.
I have 550cc primarys and 1600cc secondaries, as well as a 255lph Walbro fuel pump. The engine is street ported and I'm running a TD07-25G turbo setup w/ all the goodies. The car is a S5 FC3S.
Any ideas would be appreciated.
