I love that everyone thinks the vert is so slow. its way way way faster then my chipped 335 was..period.
I really just don't understand those comments about why would you want to do performance mods...its a convertible...
The damn car is an M3.. its a performance car, so its a little heavier and a few tenths of a second slower then the coupe. so what.
Cant we all just get along..
Slammed, get teh AA ecu, its worht the money, you cant get gains like you can on a turbo car. but $900 for 15hp it fine. you probably wont feel it much to be honest but that with your other mods will definatly be a difference.
