This is what it does, at the beginning of the video i was reving the car slowly and letting it back down, then i tried to raise it above 2k, and one of the rotors would shut off. What could cause this to happen? It bogs really bad. Thanks

 

could be your map sensor maybe

 

I actually tested the AFM on it, and it is perfectly in spec to the S4 FSM. It has an upgraded 255lph fuel pump, 3" DP, 60-1 TEC Greddy turbo, HKS SSQV, and an Aeromotive FPR.

Do you think it could be running really rich due to the fact that i only have a 3" down pipe on it right now? Do you think the added back pressure of the full exhaust system would help it to lean up a bit?

 

maby check your tune lol. with mods like that not having a correct tune would be a start. my fc acted like that when my nock box got pissed off but that car was stock.

 

check to see if all your injectors are firing. i had a bad driver and it killed my car.

 

i know all of them are firing because it sounds like its boging due to running to rich and cutting out. It will also foul the plugs after it does that on the rear rotor.

Do you think it could possibly be the pressure sensor acting up and making the computer think that its too high of boost? What would happen if i unpluged the vac line from it? Or maybe just unpluged the connector on it? It wouldnt mess anything up other than the factory boost gauge right?

 

would only running a 3 inch Downpipe make the car run really rich??

 

no. Unplug the map sensor and disconnect the vac line to it and see if it acts the same. Will it idle at all?

 

No way to control the fuel? If you just threw that walbro pump in there you are running stupid rich.

 

Yeah, you basically have a waterhose attached to your LIM. Bogging it with too much fuel maybe?
