I am not throwing any codes but I have yet hit vtec I have had the motor in since october I also pulled the plugs today and did a compression check and it read 215 acroos all cylinders, but I am running lean I believe.I bought a PW0 ECU and it has a vtec rossover controller on it I was told that the air/fuel mixture was adjusted. but if that is true why am I running lean instead of rich.? Any Ideas would be really helpful to help me fix this.
