Setting up Greddy Prospec B

[C-Rex]

Have one of these in the s14a and need to get it setup right cause its wrecking my head
On low its going up to .63 bar and then surging on an off on open throttle!
On hi its going to 1.22 bar and dont want it running that high unmapped.


Has anyone here got a good setup that they find to work ok on an sr20det without surging etc

Found this but more specific for an Evo and the fact that I dont have an instruction manual for it either:

I have had two profec b spec 2s go faulty I think iangsr20 on here had one go faulty aswell.one of mine used to spike the other wouldn't hold boost then died,both of them were set up properly by a tuner.I am now using a avcr and have no issues.it's a good possibility that your controller is the problem.I can't offer much help other than that.
