There is some throttle lag programmed into the ECU. This can only be eliminated by reprogramming the ECU (ie, a tune).
A SprintBooster does exactly the same thing that you can accomplish by pushing on the pedal a little harder. It does nothing to eliminate the lag in the ECU. Plus, as mentioned above, it decreases the control you have over the throttle (takes less movement of pedal to reach WOT).
If you have a SB and you like it then that's great. But it is not a substitute for a tune.
