Hi,
Does any one have an idea of the % power loss through an automatic box and drive line, my 97 S6 is showing 215 by at the wheels on rolling road and trying to get a flywheel figure. I've heard figures from 20% to 35% loss, the original chips are MTM 303PS which I believe is 298 bhp.
Any help much appreciated
Regards
Chris
