Ok i am new to nitrous so i need a little help tuning my 5.0. I have a NOS Sniper Wet kit that due to the jet combo i am runing a 125shot. I just tried it for the first time and it was very weak after 3 shots the car started runing like ****! I got home pulled a plug and it was black as hell and rounded, So im running way to much fuel according to my chart. I recently purchased the car it has bbkshorty headers, bbk 70mm tb, bbk tb spacer, c&L mass air flow and a bbk fuel pressure reg w a gauge on the back. Guy said it has 24lb injectors and it looks like they have been in the tank so who knows what fuel pump? I need to know from someone what to run my fuel pressure to and if i need to mess with my timing at all? Someone help lol please i dont want to see my pistons beside me while im driving

 

You need to set the timing for juice. Less timing advance and high octane fuel.

 

what was your bottle pressure? if the bottle is cold the pressure will drop which means less nitrous per shot yet the fuel pressure stays the same.

pull a couple degrees of timing for the nitrous.

i would never spray nitrous without knowing what fuel pump is in the tank.

 

yeah at least use a guage off the schrader to watch it. fp is about the most important thing you need to worry about

on 125 jets i would run 10-12* timing depending how high octane your using, and the ambient conditions

what plug gap ? i like .042" for smack

and what do you mean the plug is rounded??? some of it is gone??? your gonna melt a piston doing that. or i just dont understand what your talking about

36-38 psi with vac on is good so about 42 psi WOT
