Air/Fuel Question Hello,
I am running the mods in my sig and the N2O system is a Brand X wet nozzle kit with warmer, Dynotune window switch, fpss, blanket, purge etc. I am runnung a 100 shot at ~970psi and working on dialing the AFR. System works well.
Question is: When the nitrous hits the AFR is 12.0 and as the bottle pressure pulls down through the run, the AFR goes into the 11.9 to the 11.7 range.
Safe enough or should I re-jet the fuel or drop N2O pressure?
Also, car has 58 lbs fuel pressure and skipping spray in fist and w/s on at 3400 and off at 6k, for now.
Thank you!!!
