Dude, at a minimum, please call Clint. He can tune the PCM. I'm sure there's a lot going on in the tune that you aren't seeing other than the 4* of knock.
If you insist on not doing any other mods to the car, I don't know if you could even do a mail order tune (which is normally suggested) because it'd be waay of.
There's a lot of resources for you in Denver, use em man.
