I know the eco tune sucks unless you only drive on the highway.. I put it on last weekend and drove to lubbock anbd back...23 mpg going 65-70 with the tailgate down and fence stuff in the back. Around town it was a pig. I like the 91 tune, seems about the same mileage wise, but there is hardly any tweaks until after 2500 rpm in any of them
