Spraying your car, yea or nay

Actually, you can run nitrous without getting “tuned” for it. That’s why they sell wet kits…You can run a wet kit with the proper nitrous/fuel jets and be completely fine. I ran a 50 shot on my stock ECU and went an entire year, went through atleast 10-15 bottles then I got K-Pro & direct port.

Fuel pressure sensor? I don’t know anyone that has that…Nitrous kits don’t come with any “safety” stuff other than instructions and the proper jets to run for fuel/nitrous.
