Vapster Working on Gasoline Engines 2016 Jeep Cherokee

Been Testing on 2016 Jeep Cherokee

Jeep Says You Should get 22 mpg in City and 31 mpg Highway.  That’s a Joke!  I averaged 20 mpg in City and 25 mpg Highway.  After Installing the Vapster RV-3300 Unit I’m getting 26 mpg City and 32 mpg Hwy without any CEL’s
