Low fuel psi @ WOT
I recently got done having a 6.0 lq9 built for my car after a tuning issue blew my 25k mile ls1 up last summer...I haven't had the car on a dyno but I used my ms4 cam prc heads and ported fast 102 intake from my ls1 and had my Nitrous installed....my tuner noticed we were maxing my 42 lb fast injectors out on motor they were at 117 percent duty cycle so I bought 80 lb injectors from injector dynamics and that obviously fixed that issue...I have a walbaro 255 pump and the hot wire kit so we made the first nitrous hit on the car and my fuel psi went from 60 to 30 psi at wot I'm spraying a 150 shot off the rail...would like to spray a 200 shot but I want to know what you guys are doing for fuel delivery I don't want to do a stand alone system....is there a dual pump return style system that can be bought?
