Martins boost came in with a big kick at about 4,5k

Yeah about 4-4.5, definitely not below.

I got 215bhp at the wheels on a known accurate dyno. I think it will make about 200 at the wheels most. I only have a 2 1/4" exhaust.

My max power was at 6,100rpm, Toms will be closer to 5,500rpm. It may have the same torque, but lower in the rev range and therefore a little less power.

Depends on the dyno though. Its been seen to be a pretty subjective test where results vary alot.
