Im looking for somethin to give a little more power to our 2010 rubicon. I asked the dealer about programers if they would void the warranty and of course they say yes it will. I asked about regearing it and they said warranty void. We are running 285/70r17's and stock 4.10 rears and 6 speed. It moves ok going down road just want a little more to be able to pass someone and not void our warranty. Im not new to the market on programers and plug and play modules due to our diesel pickups we have. Im looking for something thats untraceable that will do a little more power and improve mileage. Any help would be great.
