hey guys. i have a nitrous kit installed on a 2001 focus. ive been running into a problem that i cant seem to figure out. when i spray, it hesitates and bogs down. at first, i figured it was loss of fuel pressure from the pump. i installed an svt fuel pump and it still bogs. i changed out to copper plugs but i left them at the factory gapping. what should they be at? could it be something with fuel pressure? any help is appreciated.....
