Right next week I am booking a local rolling road for a few hours or the day
I have a few remap files to try on the car and will also tinker while there to get the best power/remap for a 328i running an M50.
My friend with the US M3 Cams is coming to, again gonna do the same for his car.
First run is going to be on standard map/air filter/but decat and M50 manifold to what kind of power the M50 manifold gives, then after that remap files and different air filter options.
I will be making an extension post afterwards about power etc and what was best.
