I was just wondering if any of you have ever tried any of the peformance chips out there in a grand caravan I am looking to improve my mpg dont really care about the horsepower and all that just looking to improve my 2012 grand caravans gas miles it already get's good gas miles just looking to improve them since I do alot of driving.

 

No chips out there that I know of. Other then sending in your Caravans computer to Jet or Superchip's to reprogram. If your looking for a boost in gas saving try switching to a K&N filter to start. I've also been finding that driving with the Fuel saving button off gets me better gas milage in city so use the fuel saving button on the highway only.
