There doesn't seem to be a thread on this. Has anyone installed a Sprint Booster in their T'reg? If you did it on a T3, can you share how the installation went?
Since you have a T3, just use Sport mode. Sport mode has an aggressive remap of the transmission and throttle. It won't let revs drop below ~2000 RPM or so to ensure you are always in boost. It also remaps the throttle to make it much more sensitive (which is what you are looking for).Just to clarify - I'm not looking for a performance gain. I'm looking to improve the reaction time between when I push the pedal and when something happens. I've noticed that, often, I push the pedal to get out into traffic and it takes a second for the car to react. A few times that has almost caught me out in the intersection with no power. I'd like to avoid that.
