Anyone try "Sprint Throttle response Booster"?

I recently purchased a 2011 335 IS convertible and although I really enjoy the car I'm not a big fan of the dull throttle response of the electronic throttle.
I've seen advertised by Turner a "Sprint Booster" throttle response improvement to eliminate the lull between steeping down on the throttle and response.

Has anyone tried this device? Very curious before I drop $300 for the device how it actually works. Appreciate any real world experience out there.

What I hear is that a chip tune does the same thing and more, especially for a 335i.. For the ones who did do it, some like it and some say they took it off and just pushed the pedal harder.

I bought a differnt brand throttle remaper, but I think it does the same thing as the Sprint.

Here's what I found.

It speeds up the throttle response so the soft initial response period is shorter, but it is still there so I found I still tended to press the throttle harder because not much was happening to start with and then it all happed faster than I wanted.
I then tried resetting the throttle adaptation every few days. This helped a bit, as did the throttle remaper.

But here is the bit that really suprised me.

The throttle remaper I purchased also has a reverse setting. It has about five settings that slow down the throttle response. They call this economy mode.
When I selected the second of these settings just to try it out I found this "lag and sudden kick" almost completly gone.

Sure you have to press the trottle further but the response is more linear and you soon get used to having to press a bit harder.

That remapper sounds more desirable than most. What is the brand and model?
