I think the setting you're looking for is "Throttle Progressively". I believe most tuners will have it by one name or another for throttle by wire bikes. I played with it a while back when I had my 13 EGlide. The idea is to soften the throttle at lower RPMs but still give full throttle at higher throttle positions. Increasing the values at lower grip throttle positions did give me the impression of increased performance, but it was way too jerky when putting around parking lots. I put it back to factory default settings soon after.
As Sparkee mentioned, zero lag on a TBW bike is going to be very jerky/touchy. Every bump you hit is going to create throttle input.
And as BTSOM said, they don't go wide open immediately if you are in lower RPMs. This is done to maintain intake velocity into the cylinders and it helps the rpm's to increase faster. If it went wide open immediately at lower rpm's, it would bog down first then climb slower
