Im Just trying to figure out why my car goes rich AF in top of 2nd and 3rd.
Here is my set up
408 direct port nitrous kit w/dedicated fuel cell.
T400
speed density tune
O2s turned off.
Car na runs a 12.3 af flat accross the board. On nitrous the af goes off the trans break up to a 12.1 then down to 11.7 through 1st then when I hit 2nd it goes back up to 12.1 then back to 11.7 then starts going down to 10.5 top of 2nd and all of 3rd.
I have the dedicated fuel pressure at 8 psi. I just cant figure it out unless the computer is commanding more fuel out of my injectors in 2nd and 3rd.
Im new to this but the car is tunned by a well know guy here in the midwest.
