noob question.
would it be possible to reflash the stock ecu to account for a 3" TBE and a CAI without having to get an aftermarket EM system? i know the exhaust will throw an O2 cel until i can figure out how to make that little "extension" piece for the O2 sensor... but i'm not sure if that will mess up A/F ratios and blah blah blah.. but i was putting off getting an EM system because of $$...
