what is you're a/f ratio before spraying and while spraying if different?

 

My car is stock and the wideband was showing a 10/4 before the spray.
After tuning the nitrous we are running 11/9 to 12/1.

 

Kyle, typically for forced induction you want to be around 12:1 on the spray...N/A folks try to shoot around 12.7 to 13.2... Also a good rule of thumb is for every 50 shot you would typically back off 2 degrees of timing.

 

Yeah I have heard all of what you're saying, but hearing about cobalts #4 cylinder running leaner than the others I was thinking I might want to run it a little richer. Somewhere around 11.7. Now I have to get a new 02 sensor for my wideband.
