Did changing sparkplugs help? I literally installed Dinan sport less than a week ago and have noticed the gear will sometimes get stuck and wont upshift when I try to WOT. Just revs high and wont upshift unless I use the paddle shifters. Really havent had the issue before. Transmission is normal not sport. In all drive modes it feels like the car is only pulling 70% as hard as it used to in the 20-60mph window. Feels good in low revs in comfort mode though. I may unplug soon and see how it feels without. Probably just going to switch to BM3 though.
