Thread revival! So I’ve been having nothing but problems on my 2011 328 E91 since getting my AA retune after installing AA headers. Unless it gets sorted out soon I’m considering another tune.
Current mods....3SIM, Euro Box K&N filter, Rev silicone intake inlet, AA catless ceramic coated headers, AA Gen 2 axelback, custom resonator.
Anyone with a similar set up running BPC tune with good results? Are there any other options for tune other then AA and BPC? Thanks
