If it's nx, you will get 75 hp from a 75 shot. Colder plugs are very important, I run two steps colder copper plugs gapped at 35. I think you have a lot more margin for error with a 50 shot, I topped out the car a couple times on 50 and hit the speed limiter (very bad idea), luckily I stayed in the gas, just got off the wot switch and kept the air flowin and it was ok. I could hit the 50 shot at 3500 with no worries, I'm probably just overly cautious when I say 4k, but better safe than sorry, I would never tell you less because u might blow up and I'd feel bad. I will say it's fairly safe at 4k and up. Another benefit of a window switch is, you just arm the system and go. Without one, you need to launch, determine if you have wheel spin or engine bog, decide whether to arm it, do it or don't do it or wait til 2nd and arm it. it's a lot to do. with a window switch, you can launch at 4k or whatever, floor it, if it spins the tires and goes to the rev limiter, it'll be ok, cause it'll quit sprayin before it gets there. make sense? and also it won't spray unless you're over the low setting incase the engine bogs down. I don't have a window switch, wish i did, just too many other things to pay for first. If you have any jegs catalogs layin around, msd makes a very good window switch too, about the same cost. I've pretty much mastered the nitrous launch, but it took a lot of time to figure out where to launch and be able to decipher track conditions. Once you go nitrous it's tough to go back. I burn off a 5lb bottle once, sometimes twice a week. haha. Good luck, be safe and keep us posted
