I want hit the data initialize feature on the Power FC but I know its gonna lean out my motor. I had a baseline dyno run at around 13.5 afrs on the stock maps. I want to install a fpr and raise the fuel pressure, would that richen up the mix enough by itslef??? would timing be too much with a street port?

 

Why don't you just add fuel using the PFC instead of some hokey method like raising the fuel pressure?
