I have a 2009 m50 se just got the cobra fi2000r ive read on all kinds of forums that I can install the fi and put on my new exhaust and I'm good to go. well I receive my new fi2000 today and cobra instructions mention have to adjust pots with full exhaust add on anyone know if that's just cobra being safe. And if anyone has installed and been good to go without adjusting. Cobra base settings thanks for any info...
