I have heard mixed opinions on FMIC. Downpipes do cause error codes, but FMIC upgrade is pretty unintrusive. I will be talking to my SA when I go for service next time..

I redid my intake from custom DCI to AFE DCI with Air scoops. I didnt like having air intake being so close to wheel well, and since there is an opening i was concerned with rainy days I may be injesting water. So switched over to AFE DCI which is pricey, but has heat shield, and filters sit directly over the intake manifold. Air scoops should help with piping cool air while moving. Quality of AFE is outstanding, and Jeff from Top Gear has best pricing..

What do you guys recommend as far as FMIC go? VRSF, ETS, ER... So many choices my head is spinning. Would like to upgrade FMIC before I bring in additional boost.
