[QUOTE="EDrgr, post: 16852667, member: 113663"] All, I was datalogging a little bit last night and came across something concerning. It appears my fuel pressure is dropping at WOT to around 29-30 PSI and my AFR is creeping into a dangerous range (12.35). This is a boosted application. Also, I logged my returnless fuel pump duty cycle and it was maxed at 1.00. I have the FMS LU47 injectors and a Deatschwerks 340 pump, no BAP. Ok, where to start? After googling, I'm going to make sure I have a fresh fuel filter in to rule that out. What would be the next step...BAP/ better fuel pump??? I've heard horror stories about Deaschwerks. [/QUOTE]
