check out RR on his defence of all his mods. Put this way, i have driven REVO k03 cars at all the stages from stage 1 up to the stage 3 conversion. There is that pause before delivery, and you probably havent noticed as you may not have driven many other cars with different maps, i have and the REVO surge is more noticable than others, possibly exasperated by the throttle % input/output.
granted even if they have only changed this throttle input %ratio, but if it makes it drive like a cable operated throttle it can only be a good thing.
It would surely give you more control over the car, make it easier to feather the throttle mid corner etc etc, all for the sake of maybe having to depress the throttle further at times.
me personnaly, i think this would be the map i would go for, especially for track work
