[QUOTE="Black306, post: 9754205, member: 4780"] Looking at your log, I can see a few things. Looks like you stabbed the throttle and spun out a bit. ;) Your pumps max out at about 4975rpm. You don't have pressure drop in the logs and there is no info on actual boost, so it's hard to say what the pressure drop is. I'm going to guess that you are running 15psi of boost or more. That said, your pressure drop is 34psi or lower above about 3500rpm. Your injectors are trying to compensate for the lack of fuel from the pumps and hit almost 95% duty cycle at the top of the pull. It still looks like to me that you are having a PPRV delete issue or weak/dead pump. However, it could also be other things like turned down knob on the BAP or some kind of wiring issue. Have you done anything to the car lately? Have you had it running right at one point? [/QUOTE]
