Hi everyone, I need to find someone that could help me with my scenario, I have an S3 Sportback 8V 2015 and I am presenting the following situation. When I go to the drag track I feel that the car loses power after 3rd and 4th. The car starts with good power, but then 3rd stop pushing with the power that characterizes him. I had programming previously with APR Stage 2; then with REVO Stage 2 but the car continued with the same situation. I do not know where else to look to solve this problem. If someone had the same problem and can help me please let me know. Have a great day. Thank you.

Spark plugs one would assume.

Sounds to me like you need to do some datalogging of AFR, boost, timing, etc and see if there is a reason that it's flat spotting.
