I've had really bad experience with my sprint booster !! it locked my throttle wide open twice and i was about to having really bad accident !!!
i lost control on the middle of busy street and i didn't know why my car is acting like that. second time it locked my throttle wide open on the highway, i was accelerating crazy without pushing the pedal !!!! i will call them tomorrow.
i had it for 3 months and it was good.now it is kind a scary !!!!
that says it all.. SB is the culprit. But then again the problem is also the throttle as well maybe SB triggered it to be in that state.
Whatever the case. I think you should completely remove it and drive safely. If you really want to eliminate that throttle response I think its wise to go with FD DBW module.
So SB is nothing but signal booster that you sent out to from the throttle when you press it. It enchances the signal by 25 to 30% and in some case even up to 40%. Which means is the car think you have pressed the gas pedal far enough but in reality you have just lightly step on it.
As for DBW it basically helps accomplish vehicle propulsion by means of an electronic throttle without any cables from the accelerator pedal to the throttle valve of the engine. In simple words its just not a booster to modify pedal sensitivity.
You can check FD DBW at this link.

Guys one is just a signal booster so it does nothing except boosting the signal your throttle response sends out. For example half pedal down might relay to 75% pedal down, so the car will pick up more quickly.
Where as DBW does all of it and more but it does not do it by boosting the signal. It achieves it by tuning and programming control settings.
If you want to understand more about SprintBooster Here is a link
Its Conclusion is
The Sprint Booster is a simple amplifier that multiplies the accelerator pedal
sensor signal, making the accelerator pedal more sensitive. It does not eliminate
any significant delay in throttle response, nor does it greatly improve acceleration
figures. It does not change the adaptive throttle control programming of
electronic throttle control vehicles. It does change pedal “feel”. This change in
feel is interpreted by some as improved throttle response, acceleration, and a
change in adaptive throttle control programming. Considering what it actually
does, it is expensive.
