I have not been able to find this on any forum. Sorry if its somewhere already on the shelf. But i have a innovate scg-1 boost controller on my 2003 mazdaspeed protege, which is having an issue where the Hg (boost) doesn't read any boost over 0.0. Even when the turbo is boosting, it doesnt usually go past -8 or so. it idles at -22. And when the car is off it will just spit out random numbers. Iv taken it too a shop, they said my car isn't boosting past maximum wastegate pressure because of this issue. I plugged in a analog boost gauge and the pressure reads normal up to 6 lbs boost. If there's any more info i can give you, just ask.
