I have installed the GM stage 3 kit with nitrous, everything is working great.
My question is what size jet are you guys running, I have a .036 that is running a little rich around 10.1 AFR

 

That really depends on your nitrous setup. Are you using a bottle warmer?

 

yes I am using a bottle warmer set at 950 deg's

 

Gawd, I hope you're not setting it at 950 degrees. Perhaps 950 psi?

 

it should be right their or 1100 psi that where i had mine set in my V6 stang and it worked perfect cuz when u use the bottle it cools down so i always had it sed a little hight so i would be ready to use again. what brand are u using????

and u can always buy a few Jets in either direction for the fuel and nirtous.
