I'll be sure to update when I get it back together. Problem is, I'm replacing everything this time so if the problem goes away I won't have a definate answer on what it was.

This is one of two things if you do not have good voltage from the fuel pump rely or you pump is not up to the job .Some time's when you do up grade's to your fuel set up this will take place .
We just had to add a serge tank and a bosch fuel pump

I finally got the car back together and track ready with all the new fuel system in place. STILL dropping at WOT.... I did find out something interesting however. I adjusted the regulator up to 70 psi and now it holds pressure at WOT. Is there a check in the pump that could be bad and not working properly with the lower pressure? I'm at a loss because this has been an issue with both of my new racetronix pumps. Any ideas???

I think I'm just going to switch everything over to run E85. I already ordered an AEM 320lph pump and about to order some teflon hose. I have a quick question on the injectors though. I was going to run the Siemens 60lb injectors so I would be ok with E85 when I put my cam in, but I'll probably go FI shortly after. Would it be bad to go with a bigger injector (80lb+) while still running a basically stock engine? I'd rather not buy more than one set of injectors if possible.
