hey guys i just put my supercharger on last week and its awesome had a problem with bypass vavle but all fixed.i was just wonder if i would be running lean or not. i am running a m62 charger with the 2.2 ecotec with the gm reflash and i have the gm stage 2 kit which is 3.0 pulley, stage 2 belt and 42lb injectors. im not running the 42lb, im running the 36lb. so am i running lean or not. thanks alot guys

What does your wideband say?

dont have one just asking if anyone knew because i ordered one and i drive my car daily. i dont want it to blow up

All I can tell you is the GM reflash runs pig rich with the stock pulley and injectors. You are taking a risk by making the pulley smaller and not using a wideband without tuning

At high rpm it is more than likely leaning out to about 13-1. That's what mine did on the 3" pulley

Drive it normal until you get the wideband. Why didn't you use the 42lb injectors?
