It's outfitted with a high-speed processor, a warning alarm, LED display and an overtake boost system as developed on turbocharged Formula 1 cars. Naturally, we include a link that will allow the PRofec's use with future GReddy electronic control technology.

easy install, all harnesses included, easy to train, easy to adjust, tells you if someone has changed any settings, Overtake boost timer is great for street racing when your stock boost level is set to a more moderate level for cruizing. Just push the button and you are off. Unit holds 2 bar at stock plus up to 50% more on overtake mode. Most boost controllers turkey out at 20 psi. Much easier to use and install than some other brands (e.g. aPexi and blitz stuff)


Doesnt have some of the nice bells and whistles such as injector cycle, TPS switch monitoring, boost and hold reporting, etc.

The profec A spec is a fuzzy logic boost controller. Has great features, including overtake boost mode for extra set level of boost for a specified time count. Also has safety alarm that can be set to a specific level and will kill boost if level is overshot for more than one second. Once learning mode is completed, turbo lag is greatly reduced and steady boost levels are obtained at the setting you choose.
