Greddy Profec B Spec II

I'm having alot of trouble keeping 14 psi with this boost controller. The weather has been cold lately, so I'm sure that's affecting it. I need to know what other peoples settings are for 14 psi. Right now I just can't seem to get it. I have 10 psi on low boost very well, my settings are 45%, gain at 15%, and start boost at .56 in kpa mode. I've played with any number of variations of these numbers to try to get 14 psi but it just won't take lately. I have had it set to 14 psi very well before, but that was when it was around 50-60 degrees everyday, now its more like 30-40. Can anyone help me out?

Might try lowering the gain to like 5 or 10%. It's only like 50-60 here so I'm not sure how to help you. But I would start with the gain.

By trouble keeping 14psi, do you mean that the boost starts to fall in the Upper RPMS? If that's what you mean RAISE the gain setting. This should stabilize the Boost at upper rpms. The only thing is that if you raise the Gain setting, your boost will usually increase, so you might want to lower the set a bit.
