just sprayed my 350 iroc with my 5151 nos kit tonight and it ran awesome untill around 4800rpm then it acts like its gettin more fuel than spray blubers untill i let off. then trys to clear up but still seems to have an excess of fuel in cylinders for a second..... sprayed 3 times and same each time,,,, blows threw 1st, into 2nd and haulin mail untill around 4800 or so got back to shop opened the hood and found a slight nitrous leek on back of nitrous solenoid,,, dont know if maybe it was leaking nos while fuel was getting a steady supply and maybe riching up the mix to much....... had to get home cause wife made supper but im gona fix leak and try again we ll c i guess thanks it was 100 shot anyone know what jets would make a 75shot thaks

 

Check your plugs after the pulls? I'd hate to have it sputtering from a lean condition

 

jet chart is on NOS website ...

 

typically a lean condition that bad he would have broken something already.

I'm betting it's an ignition problem, weak coil or sketchy ignition box, maybe too big plug gaps...

 

not lean no popping or anything just rich acting gettin more fuel than nos

gona fix leak tomorrow and try again is the ignition coil a common week spot on these cars

 

and plugs are gapped at .032

 

I'm in love with your tow vehicle. Want a motorcycle? LOL

 

i just finished my cummins swap in it pulls awesome
