I had about a dozen or so cocktails today lol but I would say you need a bigger fuel pump. The stock fuel pump max's out in the 350 hp range and your above that especially with the nitrous. I think you would need a 300+ pump like a AEM 320

I figured that I would need one by now was just uncertain of the one I want to get. I plan on pro-charging this thing when my wife calms down about the amount of money I will have in it. Does anyone know how much the BBK 1863 pump is rated for? I know it is a 300lph pump.
