I am looking into finally upgrading my stock FMIC. After some price/reputation/fitment research I am leaning towards the Active Autowerke Sport.
I did some research but have found little in terms of reviews, IAT comparisons, HP/Tq gains with FBO cars, install and fitment, especially on N54 135i's.
So, has anyone personally had experience or can you point me to a thread with some more info?
Thanks!
