Ok so i got my charger mounted up and did a few pulls. I had noticed that i keep fouling my plugs and it's now a problem so, after looking at the a/f it seems to be too rich. When in boost it was running 11.3 - 11.5, I think it should be 11.8 - 12.3 (correct me if i'm wrong.) This is my most recent pull and i'm still getting way too many knocks so please tell me what you think. I pulled some more fuel out from 65-7500rpms to bring it up a bit and i will post that log later in the day. Thanks for the help. Oh yea, it's an 03 ep3 k20a3, 2.5 mid pipe and comptech ice box.

If you have a Jackson charger this could be that the shaft within the charger is on its way out ( production fault ) and this sets the knock sensor off as the frequency is about the 10khz mark .
check the end seal on the charger ( behind the pulley ) if it is leaking oil get it checked .

other than that what size pulley are you running ?

just seen you are running 4'' pulley
