You are not knockin at idle. There is not enough load on the motor at idle to create detonation. If you are running more than 15psi of boost at allowing the stock ECU to control timing then you are probably getting knock. Here is what you need to do, build you a set of det cans, I posted links to them on other threads somewhere. This is the cheapest and best way to see if your motor is detonating. Now, unfortunately you are going to have to buy something to control the ignition timing. Since your using portfueler you will need to run the MSD-DIS2 to control timing. I know if sucks but you dont have a choice. Check to see if your getting knock first but I will almost promise you that you are.
