stock fuel rails? 800rwhp is around the limit on those I read somewhere... or did you upgrade fuel rails with the rest of the system?

Didn't you go with the rodeheaver fuel system? If so i would check voltage at both pumps, this system uses dual FPCMs if I remember correctly so i would check it pre and post FPCM and make sure you have the voltage you need. Try checking it with just key on and then key on WOT. It sounds like your pumps are staying on the low voltage setting and not getting the extra juice when you go WOT, hopefully its as simple as a bad FPCM or another loose wire.
Keep us updated were all pulling for you!
I didn’t even think about the voltage. I’m going to check that tomorrow. Thanks man!

I was testing the fuel pump wiring harness for resistance from the ground to the battery (negative side) and found that the pin in the wiring harness would push out when pressure was applied. So I watched the wire as I plugged it in to the fuel pump and sure enough, the wire would move out of the connector as the male end moved into it. I tried everything to get that pin to stay in the connector but failed. $60 for a new one

dude the shit is nuts ..i am around 6 months into boost and i am finally getting some reliability finally from all the ****ing mistkaes the shop made i had to correct last 6 months .... but once its sorted it will be worth it so u gotta keep going
What fuel system do you have?

I tested both my FPCMs’ voltage and at partial throttle they are around 14.3 and at WOT voltage drops to 13.8...
I did the test at each plug that goes into the FPCM. Now to figure out what’s causing the issue.
