I hope you get it sorted mate but your making better bhp than me but as i sed flywheel figures can be whatever the guy doing the run wants it to be. The guy who did mine changed my losses from something like 33% to 50% and my car was then running 290bhp at the fly!!!
By the way what was your at the wheel figure think mine was 186bhp.
not got the graphs to had butwill check and post them up and i'll try and get the graphs up to so everone can get a look
