Does the Ultimate control boost in the same fashion as the stock ECM? IOW, does it look at a boost target and adj. from there? Does it have it's own boost target or does it use the stock target and just add to it? I'm asking because I would like to be able to build more boost at the lower 2K-3.5K RPM. If I throttle mine it jumps to 15lbs then backs down to the boost target real quick. No knock showing on the Datamaster. BG???
