Need Help with Dyno Results
The car is an 03 coupe, A4, 3:15 gears. It has Kook's LTs, Kook's x-pipe with hi-flow cats, blackwing with air bridge and smooth coupler, and corsa exhaust. No tune yet but I recently changed plugs for NGK Tr55s gapped at .55.
Look at the attached chart. The car breaks up bad starting at about 4800rpm thru 5500 rpm. It ran 322.2 rwhp and 352 rwtq but these were just spikes. It is also running rich - 12 afr and it drops from there.
What would make the car break up like that? The tuner thinks it might be something mechanical and suggested I find out what is going on before doing the tune. He thinks its sensing a knock but the car doesn't throw any codes and seems to run strong.
Any suggestions?
Thanks.
