Yeah the stock tune is ridiculous. I averaged 15.5mpg which is definately the best mileage I have had pulling my boat. There wasn't hardly any wind today at all so it was a good "true" test of what it gets. I would say that it was around a 1.5-2mpg increase. What else did you notice about his towing tune over the canned tune if anything? Also I want to fill up with 93 octane and run the canned level 3 so do I need to advance the timing? If so how much?
