I recently swapped over from an A4 to M6 and now I am having problems with my motor staying reved up to 2200 rpms until I come to a complete stop. Even when I am completly stopped it takes a couple of seconds to idle down. My car was tuned before the swap and had no issues like this. I used HP tuners to convert over to a M6 program. I basically just coppied and pasted my tune over to a stock M6 tune. I can't figure out what I need to change to make this quit. Any suggestions are welcome.

 

Did you copy over the "Idle>Idle Airflow>throttle cracker" table from the M6 file? Try that, also you may want to compare the "Throttle Follower>Decay (P/N)".
