It's detecting knock (or you have a bad boost solenoid). The correct plugs may indeed correct the probl;em. Otherwise, Shiv is likely right in that you either have a knock-prone car, or it thinks it's detecting knock, which has the same effect.

I am hopefully going to S-Squared on Saturday. Nate is going to have a look and dyno tune. I hope it is not a knock prone car. We are going to try the new plugs.
