From what Ive expirienced you can pretty much toss the manuals out on EBC's. The translations are lacking. EVERYTHING has to be set properly or it wont work correctly. Gain should apply regardless of mode. Again I've never used your specific model but they all share similarities.
Come to think of it that was the problem on my Profec. If you increase Gain on the SpecII's you also increase boost. It's probably the same for the Blitz.
