Tuning question. Any help appreciated!
Since this forum is the best, I decided to try and find some help here. I have a 2013 Audi TT RS. I have it tuned with stage 2 APR software. Now, my friend has a 535 JB4 tune without any issues. I am having a problem with the tune on my car. There are multiple people with the same issue. I have what feels like a miss fire when I go 75% to 100% throttle but it is not consistent. I have tried re-gapping my spark plugs but to no avail. No one is able to figure out this problem so that is why I decided to post on here to see if any of you have experienced an issue like this on your bmw. I would appreciate any feedback. Thanks.
