Greddy Profec B Boost Controller
Just got mine in the mail today and was reviewing the instructions. Does anyone have a website on how to install this thing or something I can look out to make installation a little easier? The controller itself is so small as the pictures on the net go my thinking it was the size of a car cd deck. Anyways if anyone has a useful site please post it. Ill get some digital pictures of it for you as well and post them later tonight.
Thanks

Would you see any difference in boost response running through the single port wastegate? Like higher boost, quicker spool. I thought you had to go to a dual port wastegate to see any differences. Anybody care to chime in?
p.s Dan I thought you were going to sell your cars?

Ok so i installed a profec b on my 88t and it was pretty easy to install. I by-passed the CV. I plug the profec b in this configuration.
-boost guage hose to greddy control box.
-bango bolt to in port of greddy module.
-out port to wastgate.
-ad power and ground.
Now i'm not finished tuning it yet but i can't seem to properly control a low boost setting to about 12psi??? But i am getting good fast boost response considering i have a completly stock car with a steve r chip.
These are the boost reading i got.
1 gear: 5psi at 3100rpm 13psi 3500rpm drop of to 11psi after 5000rpm
2gear: 14.5psi from 3000rpm to 6500rpm
3gear: 15 psi all the way baby...
4gear: 15-15.5psi up to around 5000rpm than i ran out of road so i can't be sure if it last up to redline. But so far with not a perfect set up and with the boost rising rate set at max, i get great boost response (0-15psi very fast) and stiks
right at 15/15.5 and i don't get any boost spikes.
So i can say i'm happy with it becose it reduces my lag and i hold more boost longer. I will be doing some more testing and taking notes to see if i am really getting longer boost.
