Yes, but I don't live in boston
I'm sure there's plenty here that wouldn't pass a boston, or baltimore, type inspection (non-oem air freshener?).
re: report, well the mrs took it up to traverse city, said it was nice to have on the hiway. It isn't super sensitive with this setup. It helps if you hold the throttle with your foot and pull the knob out till it hits the stiff resistance. For fine tuning you have to help the pedal with your foot (really light taps or lifts) while turning the knob.
Not exactly sure how to test it, what to compare it to and where?
