I'm running 24LBS Injectors with 70 mm T/B and a 73mm mass air flow meter with calibration tube for 24lbs injectors, 155lph fuel pump. Any idea were to set the fuel pressure to start.
39- 40psi is stock spec. This is what the injector flow rates are calculated on. 30psi is a 25% decrease in pressure. This makes a 24lb injector act like a 16lber. Then the ECM goes haywire trying to lengthen the injector pulsewidth to correct it. But it can't correct that much, and you end up with an injector duty cycle that's too high and the injector basically stays open all the time.
interesting......i dont know to much bout it i just got the car like 3 weeks ago and thats how its set up i havnt taken it to get dyno tuned yet to which i'm sure they'll fix all that **** but thanks for the info somthing i'll have to look into....
