Hello Guys! I have a AMK S3, my problem is that I think my car doesn't go how it should really go! I have a friend with a 225 MK1 TT, fully STOCK! And we tried some days ago to compare the cars and... He goes EXACTLY the same as me! I have those parts fitted in my car: 42DD 3" Downpipe and 200cells cat Milltek resonated cat back Forge Air intake and all hoses in silicone TFSI Coils pack Forge Turbo L tube non resonated ITG Maxogen air filter N249 bypass RS4 NGK plugs Revo Stage 2 map As you can read, the differences between the two cars are not little... I know the TT has a totally different aerodynamics compared to the S3, but this sounds me strange! Hope someone can help me! And sorry for my not perfect english, but I'm a swiss Guy!
