i have sprint booster. but i noticed on the website it has a switch now?

is that any different from my old unit?

 

thats a good deal right there, i might sign up

 

The difference is that its selectable. Some people prefer Stage 1 with is a step up above Stock sensitivity. While the older sprint booster will be more inline with Stage 2 with slight tweaks. We always attempt to improve our product based on user input. So you may notice a benefit. If you sign up early for our track day we can see about getting you into a new sprint booster to try out free while the supplies last.

Register early since once we fill all our slots, thats it.
