i have a 2002 ss slp and will run a 125 and 150 shot. what jetts do i run.

i am going to try for the 125 hp shot: 55 fuel, 35 nitrous
150 hp shot: 63, 44 nitrous

do ls1 motors usually run rich or lean. anything else i should know. thanks

Whatever brand of nitrous you have you can check the jetting schedule and it will tell you for GM's..run a colder plug with about a .035 gap...one range colder will do....lean or rich...most are tuned to run perfect...from the factory they come pig ass rich though.....with anything under a 150 shot you do not have to worry about tuning anything though...

so i can put in some tr6s and run the 150 shot without a tuning worry?
