Greddy ProfecB install help/questions.
Last week or so my FD has been down while Ive been installing the latest few mods Ive accumulated. Yesterday I installed my Pettit Unlimited ECU, in addition to the PFS SMIC and intake. Drove the car for about an hour after than and it ran great, no problems. So today I installed my profecB boost controller ( old style, 3-****. Balance/low and high settings) I installed the underhood box as how this picture explains:
I do not have any pre-spool controller. Anyway, it seems that even on the lowest setting, I am seeing ~15psi boost. Is there anything I couldve done wrong that could be making these results? thanks..

Im having the same problem with my HKS electronic boost controller. Is there a switch on the controller for an external/dual port actuator and internal(single port) wastegate?? If so, make sure its switched to internal if your running the stock twins.

Thanks again for the help, I got re-routed all my lines today according to diagram #2 on this thread:

It works great now, I set my high boost to 13psi ( was going to set at 14 but wanted to leave a buffer for possible spikes), and car feels much faster than before. I cant even roll on the throttle to WOT in 1st without breaking the tires loose, and these are my new Falken FK451 275s
Im heading to the drag strip Thursday, hoping I can break 12s with it. I think traction will be the main factor, it definatly feels it has the power for it.
