Ute has a custom tune already!. I've read a few articles to the effect of efficiency loss and basically you need a re-tune. I live in the country so doing a trip to the city is kinda out of the way.would be great to know what the outcome will be.Knowledge will be appreciated,Cheers,Hazyco -_- Link to comment Share on other sites More sharing options...
