Wanted to share my Timeslip on my first successful Track day when everything on the car finally came together!

2012 BMW 335is DCT STOCK CLUTCH PACKS
Car has not been on a dyno
Getting drag radials on 17s soon low 10s possible?
Tried to go for 10s and up my launch slightly on last pass and spun launch. could of up boost a pound and stayed with the 2.1 sixty but didn't have time.

Feel like this is one of fastest passes with street tires. Think I could of easily had a 10 second pass. let me know what you think

Your timing takes ages to recover after a shift because the actual is overshooting target and the boost target is doing wacky things so the tune has room for improvement.

I've managed to fix the boost ceiling issue on DCT cars so you shouldn't have to use boost scaling once MHD fixes it at their end.

yeah 3rd gear timing took awhile to recover, sometimes that happens randomly. Overboosting slightly after gear changes seems to happen often
