Hello!
I have been having some wierd problems with my car since going stage 2. When I have the S-mode on the transmission and do a kickdown etc I can almost feel the car lose power when its nearing 4800rpm and it will give me the code P0087 ( Fuel Rail/System Pressure - Too Low) However, this only happens sometimes. Most of the time the car will pull really well. My tuner has logged the car after countless pulls and he couldn't see anything that had to do with the software. When we logged the car we could se that it would run out of fuel in some logs. HPFP looked fine, no metal parts etc.
Parts changed:
Fuelfilter
Darkside CP4 meteringvalve (It got alot better after changing this metering valve)
Injector seals
The thing that makes it harder to solve is the fact that for example yesterday I was driving my car home and beat on it pretty well and car was doing perfect and strong as hell. After ALOT of pulls I got ready to overtake 2 cars and at like 4800rpm (ish) car got the code P0087 and glowplug light started flashing.
Any advice what it could be? What should i start looking for?
