Orange data is Fuel Pressure, Green data is Boost
At the peak of the boost is 21.1 lbs
Fuel pressure dropped to 43.6 lbs
TPS was at 59%
Injector duty cycle was 96% (yikes)
AF Ratio was 11.6
Alky was on
No ESC Retard
Stock Fuel Rails and fuel lines
I have a Walbro 340 pump with a hotwire kit so I never thought I would have to worry about fuel supply with mild setup.
I will start with a new fuel filter to see if that is the issue, I also have an Accufab regulator that I have not installed yet....I dont think it is a regulator problem as the FP follows boost well until higher boost levels. On this run the FP followed the boost 1:1 until about 12 psi of boost then trailed off, the FP caught back up when I let off the throttle.
Do the Accufab regualtors have lower resctriction than a conventional Adj. FP Regulator?
