Anyone tried the Sprint Booster?

Has anyone installed a Sprint Booster on their X5M? Although this truck has gobs of power, the first few mm of accelerator pedal travel is a little sluggish. M mode helps but I'm used to instant and dramatic response from my 1M. I know the Sprint Booster remaps throttle position. I wonder if this would help. Thoughts?

Some say that after awhile what the sprint booster accomplishes seems to fade away. It could be that the perception that they have has changed.

I'm just gonna say that I've tuned my own cars in the past with a full standalone ECU (LINK), to a piggyback system (TurboXS UTEC), to an OEM reflash using OpenSource software.

ALL of them allowed me to re-do the pedal motion and rescale it to really any value I needed. If I want WOT to be at half throttle, I could do that via simple programming.

I would suspect that a proper tune would do this, and you wouldn't need a band-aid product that simply re-scales a simple potentiometer function.

That said, knowing what it's doing(re-scaling a value), and what you'll gain (Nothing). Don't bother. Get a proper reflash

From time to time, people are selling used ones. If you wanted to try it, try a used one and if you don't like it, you can resell it for what you paid.
