Anyone (besides me) dyno tested a biturbo V12?
I was trying to dyno test my tuned '03 V12 CL600 today but I was unable to get a torque measurement because we couldn't for the life of me get the Dynojet to pick up an injector or coil signal for RPM reference.

Anyone done it? If so, please tell me where you picked up a good clean signal!

Thanks,
Dave

What did yours dyno out to with the Stage3? Mine was 504 at the rear wheels.

Did you happen to do a "before"?

Hmmm... by that math, $6400 bought me a 3.7% increase.

Hey absent, which of the before and after numbers, if either, was with the Brabus quadpipes?

Any other physical changes?

Well, all else being equal, looks like the exhaust is worth about 20 rwhp over my car.

Surprised it made 486 stock though! I knew they were underrated, but that's quite a bit!
