I have a very similar setup and at 1.0BAR was making 334.7 RWHP/378.2 RWTQ. I have a lot less miles too and my compression numbers were all between 152-158 for all cylinders. Something is different about your car though. My dyno run was done outside in 95 degrees though so maybe that is it. I would have hoped for more than 9 WHP gain though.
