False readings? What are you smoking?
My car was backed onto a single axle dyno. Automatic tranny Crossfires have no problem on the dyno. It's the manual trannies that have problems.
I made 263 hp at the wheels with a factory rating of 330 flywheel hp. That is right in line with what it should be.
The SLK 32 has different cams and is factory rated at 349 hp. Expect it to dyno higher. It should dyno in the neighborhood of 280 to 290 hp.
Look down the forum a thread or two. You'll see that I ran a 13.27 @ 105 mph at the Texas Motorplex.
