Oh my sweet lord. Did you just say "noz"?????[:@] Please, avoid that at all costs.

27 lb injectors??? Never heard of them. I assume you mean 24 lbers. When I'm off the bottle, my fuel pressure is set at 38psi. When I spray, the nitrous regulator ups the fuel pressure to 80psi or so. That's with stock 19 lbers.

Yeah, what he said. OF course, I'm spraying 110 shot with stock injectors and stock pump.

Well, what are you waing for!?!?!?!?!?!? I picked mine up for $200 used off the Corral. Has been working perfectly for 2+ years. Just installed a bottle heater this past weekend.
