I'm not too sure about the accuracy of that dyno. Go back in and change the transmission loss to 0 to get RWHP figures,but I still wouldn't trust it. Take it to a real dyno.

What do u mean? getting on what in the summer? The average loss to the wheels through an auto trans is 17-25%. That's not the dyno,thats just what cars with auto transmissions seems to experience.
