Just installed the sprint booster and what i can say is SUPERB! The device are not add ur HP or whatever but it makes ur car more responsive even on low speed. Really fun to drive, makes u think that u have supercharger..now i have no problem to take off at traffic light anymore,no need to press hard..just a little only and the car will GO...heheehe :twisted:
Worth every penny..reccomend to others member..
