There is nothing that would cause a reducing in fuel economy other than your right foot, tune or no tune. If you drive both an untuned and tuned car hard, the tuned car will get fewer mpg. Both driven casually, they will see the same fuel consumption.

One thing you can check is to make sure your o2 modifier wires are removed in the harness as newer DME software versions took offense to this function. And this could possibly cause poor fuel economy. All of the harnesses made in the last 2 years have had these wires removed. But it's worth checking to see if you still have it installed.

Im guessing your enjoying the hell out of that procede. your MPG will go down if you like to go fast.

Procede wont diminish your MPG, but im guessing going WOT with procede will obviously be less fuel efficient then stock.
