Anybody using the old Trust Profec(digital model) on stock seq. turbos.Any comments would be welcome,found one cheap not sure if i'll get it if it doesnt perform well on FDs.

 

Profec A or Profec B?

 

Most of the old Profecs are pretty easy to figure out. Post pics or specific questions once you get it and have figured out what you can.

Profec A.any info on how it performs on FDs twin seq set up?I've tried it on a S14 (SR20DET) seem to work well ,but i would like to know if its any good on FDs.Done search on this forum nothing about Profec A's

 

Ditch it. The A is a big pain in the butt on the FD - you have to have PERFECT boost control (ie, no creep) for it to lock in properly and control boost. Any creep, and it throws your boost program out.

I've known a number of really sharp guys who've tried to figure it out - it's a design flaw of the unit. That's why they're easy to find cheaply - no one wants it.

For the FD, I'd recommend getting something else - Profec B, AVC-R, most anything.
