Jeeper Sleeper - Smooth Boosted

 Modern Muscle recently installed a new Smooth Boost system in the Jeeper Sleeper. So while we were at the Summit Motorsports Park for the Street Outlaws No Prep Kings race, we decided to do a little testing and tuning. Thanks to Smooth Boost, the Jeeper Sleeper is now even more efficient at taking cars that line up next to it out to eat at Gapplebees!
