This is why my truck had the best mpg on the 91+ Performance Tune.

Mine always got the best on the highest tune, but like you said, you have to keep your foot out of it. Which, is really hard. Haha

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

It appears you may have over-size tires on your truck. If you installed a lower ratio gear set, I would bet you have no idea about what the actual ratio is. In any case, over-size tires and lower gears are not a good combination for fuel economy. I don't think a tuner will help.

The manufacturer says in the owners manual that it's ok to use 87 octane but they recommend 89 octane. Personally I would like to know what their test results were (if they performed one) on both levels of octane. When a specific recommendation is made, I would like to know why. Especially when there are 2 options.
It may be ok to use 87 octane but if you get lower MPG then the cost savings may not be worth it.
