Hey whats going on, Iv been tuning the car and had everything pretty good, with out the nitrious, I put the tune in for the 42.5 injectors and scaled the maf .94 which helped alot, I got my tank filled and hit the button and car misfires like a bitch and kicks out, the only thing that i noticed is when im on the nos, the 02mv go way low like 45-65, what is causing this mishap. I posted the scan and my tune, thanks for any help.
