Today my dad (04' V8 RS6) and myself (84' Ur quattro) went to the rolling road. I was pleased as punch with a calculated reading of 205 bhp at the flywheel and 245lbft. (stock 200 and 210lb ft)
However, Dad's RS6 was approx 100bhp and lots of torque down on stock, and on top of that it has a MTM chipped ecu and gearbox so should be putting out closer to 500 flyswheel bhp.
The screen calculated 400 flyweel bhp, but the operator said that as it is an auto that is an exaggerated figure. So it is quite possible there is only 350-380 bhp from what I understand, the car doesnt feel very quick. There was 200bhp at the wheels.
The Mass air flow sensors were replaced when the MTM chip was fitted as it was down on power, that was approx 10 months ago.
The car is going back to the rolling road for a day for a check and probe over to see if they can find any faults. Not sure how sophisticated their fault code reading etc is though.
Can anyone help/share their experiences? are there any particularly suspect areas/mechanical failures to look for.
