Just wanted to get an opinion as to how BMW NA warranty is affected by installing third party mods from reputed dinan / ac schnitzer parts?
I am looking at the free flow exhaust, the performance engine software upgrade, and the cold air filter. That should push up the stock 184 hp to a cool 195 hp @ 6000rpm with a modified (less delay) fly by wire throttle !!! The best thing is the max torque ranges between 3000-4000rpm !!
