Does anyone know if an IAC valve code would cause my turbo car to break up while boosting, I have tried everything to get rid of the AIC valve code the only thing I have not tried is to repin the wires to the ecu, Im running a JDM GSR block with a JDM CTR head and I have 9.5:1 compression (the compression tester reads 180 across after warming up the engine) if anyone ever had this problem and knows how to fix it let me know.
Thanks
