i have one, it was an old school way to get our cars to handle bigger cams and such, just like a fox stang.
the fan controller is SWEET, i can set my low and high speeds independently of each other....but now adays it would be far easier and cheaper to get a tune.
pro-m made the kit and the gen1 kit was like a grand....it is a pain in the ass to instale too, just an old mod that's time has passed.
BUT...... if you had one given to you or got it cheap id throw it in
