My check engine light is lighting up when i start to get some boost
after it turns on my car seems to be lacking a bit of throttle response
and doesnt like to stay at a constant rpm. what could it be?
My Setup:
SOHC zc
VJ11 turbo @ 4psi
FMIC
Vortec FMU
Ebay Fuel Pressure Regulator
Ebay Bov (To atmosphere)
350cc injectors
walbro 255 fuel pump

i was maybe thinking it was the bov but im not sure ive tried adjusting the spring energy but no luck

 

First you need to see what code is stored. Second i bet you are super rich. A FMU is not real fuel management. At least run a AFC Hack. Is this OBD1 or 2?

 

well im running obd0 and its flashing 7 and 20
i looked up the code and it said it was the tps sensor and electircal load detector......

 

Never mind i found out what it was i replaced the tps sensor and it was all good
