I installed a Haibec PROM in my '90 a couple of months ago.
My calibrated "Seat O'Pants Dyno" tells me that I've got more power. Not a lot, but definately more bottom end response as well as slightly more power at top end. I get wheelspin in first gear on hard acceleration, as well as wheelspin in second gear on my patented "3rd Gear At 45 Down Shift And Go FAST". It never used to do that before...
If you're expecting gobs of more power, this probably isn't the correct mod for you. 4:10 rear end gears will make the car seem like it has a lot more power, but the drawback is that you'll have to shift gears a lot more than you do now.
I bought the PROM more for the idle improvement and also to deal with a cold start problem that I was fighting, which it did nicely. The CAGS removal, the temperature moderation and the additional HP were NICE side benefits, not the primary reason for the upgraded PROM.
