I have a sprint booster and I love it, it removes throttle lag for the most part and you have the option to set it to how aggressive you want it to perform. The only thing you should know is if you have a performance programmer like a superchip you have to turn off the throttle tune in the superchip as it will interfere with the sprint booster and make your Jeep take a second to decide which programmer to listen to and it just acts up. Once I turned off the throttle tune in my superchip I haven’t had a single issue and both works great together.
