I’m just starting to tune my recently installed TSI turbo kit and can’t seem to get my AFR to 12 at full throttle. I have the Attitude industries fuel controller and 3rd injector setup, I can only get it to 12.6 AFR with all fuel settings maxed out. I’m running around 7 psi. I am going to reach out to Attitude in the am and see what they suggest, but any help would be great. I’m thinking it’s either a weak or plugged fuel pump or the controller needs to be remapped. Any suggestions?
