Thanks for the informative review .... Best of luck with your 'new' investment.Just got my ECU in and relearned the IAC valve, took her for a ride. The most noticable difference is the idle, it's awesome and it takes a lot less throttle to do what it used too. It accelerates very quick and it's very smooth on acceleration and decel . I did pick up a little bit of popping on decel, but it sounds good. Not the same as pre-pairvalve removal. All in all it seems like a good investment.
