What do you need to know? I use the Profec B (original series), and love it. It basically has a self-expanitory wiring harness for the head unit and the solinod. Wastegate plumbing depends on whether you have a single or dual port WG. Tuning is a snap. Turn the sharpness **** as far right as you can go without getting spikey boost (about 80% of max for me), and the adjust max boost with the boost control ****. Turn it up when a Z06 pulls up next to you. Turn it down when a Mustang pulls up next to you. I set the DIP switch by trial and error, since none of the settings in the manual worked on my car. Sorry to be vague. If you have specific questions, I may be able to answer.

go to greddy.com and download the manual, its very easy. However like tom said the settings on the back wont work well, even though we have an external wastegate it works more like an actuator type.

Tom how do you have it set in the back?i've been playing with it but i am still getting inconsistant boost.
thanks

I get rock solid boost with the Profec B. You need to turn the "sharpness" **** down if your are getting bouncy or spikey boost. My sharpness **** is set at about 80% of max. Any higher and the brain tries to adjust boost too fast, resulting in over-compensations (and non-steady boost). My car is in transit from the East Coast to the West Coast right now. When it arrives (soon I hope), I can tell you how I set my dip switches. I should also have a copy of the manual, but I have to say, (a) it is in Japanese, and (b) virtually none of the manuals settings proved correct for the 951. As soon as I get my car back, I can share with you exactly how I have it set up. If you search the old mailing list archives, I know I had posted in the past about how to set the dip switches and how to route the hoses.
