Mod list is up to date. I have been searching and haven't been able to find an answer. Also have been looking for videos of fuel cut but I can't really hear the fuel cut in the video. I made a video today and you can't hear it on the video.
Background:
Vacuum line from the WG to J-Pipe (no MBC or BCS) is kinked and zip tied so it stays kinked. Without the kink, I can only run 5psi. I have tried a known working WGA and no change.
So, my vacuum line is rigged up. MBC will be here tomorrow in the mail. Now, he is my problem...
I get what I think is fuel cut. At least I thought so before today. I go to the track for Test & Tune on fridays. I have to feather the throttle the whole way down the track. Or in a pull on the high way. Almost as soon as I go WOT, I get fuel cut. It sounds like..a popping noise, and the car stops pulling, so I let off, get back on the throttle, and it's fine as long as I don't go WOT. Keep in mind all this happens very quickly, like within a second.
I usually get this "fuel cut" when flirting with the 15psi mark on the boost gauge. But today, this has happened at around 12psi. Also, just starting today, another problem occurred.
Say I am in 3rd gear at 2500RPMs. If I press the throttle in a little bit, slowly get to 3500RPM, then slowly come off the throttle, it will pop/misfire/cut out. This definitely seems related to the fuel cut thing.
I have a Walbro 255lph fuel pump and can smell that I am running rich. No, I do not have an AFPR or SAFC. It seems to me I shouldn't hit fuel cut until at least 16psi. So, what could be going on here??
