Had my B6 S4 on a dyno today and we were mystified at the power it produced.
294 @ flywheel
207 @ Wheels
277.7 ft lb @flywheel
Each run was better than the last which the operator suspected was the cats being cold. We had a problem with the traction control at first but that was sorted, I thought it might cause agro as its a tip but Nick the operator didnt think this is to fault.
Im guessing/going to check the MAF - This can be read on vag com
and a quick scan looked like it wasnt flowing freely (anyone able to tell me what I should be reading on vag com)?
What other things can I check before I get worried
