Hello. First off, good looks to Cobb, used to run stage 2 on my 04 STi and loved it.
Ok, my questions. About to pull the trigger on the AP and just want to know (based on conflicting posts I've read)
1) Is there a performance decrease or problem with using BMS intake? If not, I'll keep it on, if so, I'll go back to stock airbox?
2) Just want to clarify that a CBE (interested in the Vanguard) will not hurt or help performance - it's basically for look/sound.
3) Regarding ROM - I have a 2011 335i xdrive, is there any way to tell (call the dealer?) what ROM I have and if it's going to work? Do the AP units ship w/all the latest ROMs?
4) If I remove the tune and revert back to stock map, can dealership tell it was ever mod'd?
That's about it ... thanks!
