I had it briefly installed on my 3400 hybrid engine. Seemed to work great but I never really got on it because I never finished the tuning. Ive decided to pursue other things so the car this was in will be gone soon and I dont feel like messing with installing it in my 91 at the moment.
Heres your chance to take advantage of my lack of motivation/time.
PS: DO NOT use this post to ask how you can make this work on your engine. If you REALLY wanna know you can start a new post or PM me. Be forewarned though, its not a bolt-on mod.
