    Getting 5-9 degrees of knock as well, from what I have read 11PSI is excessive for a stock pulley? I am trying to figure out if the KR issue is related to the boost or not.
    What PSI should I be getting & what could cause the excessive boost?

    Is this a top swap?

    What altitude, temperature, humidity, air density etc etc all play a part in boost level. So does sccuracy of gauge.
    I drink..so consider that when reading my posts.
