I am wondering is a MBC or EBC will help, once I do a romraider tune, im sure this will smooth out, but the GM BCS.. its still on my mind like it will help because of its more comple nature than the subaru OEM one...
You can't just throw a larger tmic on the car and expect it to run fine. You need to tune accordingly for the larger top mount.
