Hey, I need help trying to tune uberdata with my turbo setup. Im using a b18b1 with a t3 turbo, 450cc injectors, and a Walbro 255 fuel pump. I had it running well before I installed the pump, but once I installed it, it dumps too much gas into the engine. What do I change to make the pump work?

 

Maybe the pump raised your base fuel pressure. Get an adjustable FPR and lower it.

 

Actually, if you don't have a FPR, you can use a gauge to see what your new base pressure is. Then change it accordingly in Uberdata. There is a place to input the fuel pressure in uber. I think it's set to 42psi by default.
