Warp, I'm not saying 20 HP and 10 TQ and a couple of MPG improvement are fantastic, but for $325 retail ($275/$250 with military and forum discounts) it beats a couple of thousand or more in pipes and intake and PCV and tuners and trips back to the tuner with every change. The AFR Plus is an average mans devise. It does one thing and that one thing makes a big difference in performance. We don't have to be techies and scientists or guys with unlimited resources to make extra power. Dobeck Performance AFR Plus does all the work for you. Just put it on and enjoy the boost and adjustability when you do decide to do something different.
