Perhaps there is sufficient carbon build up on the pistons (and valves?) that the compression is greater than the good book suggests is normal. Have you had a leak down test performed?

Yes, had a leak down test performed. Perfectly normal. As I said in the other post, the car puts down 170HP to the wheels, which is about right on for what I have (Dinan chip).

I mean, we're talking about a 25% difference in what the site suggests and my (and some others) results. I would not expect the engine to be performing as well as it is.

Someone else said their dealership also stated 200psi as normal.

Greg.
