hi i was wondering if i need a professional tune if i get the following items installed into my car: ams fmic, ams uicp, ams licp, buscher exhaust, cobb downpipe, and a harman motive intake? also is a cobb accessport necessary to have?

well you will need a tune - yes...

I would be getting a pro-tuner todo it, someone you trust local in your area.

Cobb AP isn't necessary, your tuner should be able to advise if you need anything...
