What are you talking about? Are you trying to say that the increase in power that the OP feels is due to BMW changing his spark plugs?! I agree, the cooling portion of the upgrade won't give the additional 25 HP that BMW claims; the reprogramming of the ECU will, and that is included in the package.
What I want to know is if Shiv or Terry will have a special tune for those with the Performance Power Kit installed.
