clutchmasters lightened flywheel


i just installed my N1 catback yesterday, and when i gun the car....it hesistates and startes popping like crazy...i haven't pushed it even passed 7g's yet, cuz it lags so hard.
I don't have an air/fuel gauge installed yet. so i can't tell if i'm running lean or not.
but anyways,
what setting could help this situation alittle until i go to a dyno?
what can i set my cam gears to also?
i pulled off my o2 sensor and the plug was white..what does that mean?
if anyone can help.
also when i input all the settings i have to inialize it then take it for a run? or how do i set it properly? thanks guys please don't flame i'm new at this, but i want to learn

 

what is your timing set at?

 

its prolly set at18, but i put it back to 16 degrees...but it's still making a poppoing noise.

 

try changing your o2 sensor and see if that helps. if its white, that means the engine is running lean.

 

ok..i'll do that when i get some more money...i didn't know that they were that expensive
