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?

If you fill with 93 octane and run a 91 octane canned tune, you should be able to advance the timing by 1 point in the custom options menu. (That's if your tank is FULL of 93 octane. If it's half 93 and half 87, you're actually using a blend that is close to 90 octane, so leave the timing alone till your tank is really full of the high priced stuff). Bill can, of course, write you a true 93 octane tune that will take full advantage of the stuff you put into the tank, because it tweaks more things than just timing.

If all you pull is a relatively light boat, 2000# or less (and it sounds like that's what you have), you can probably use any tune to pull it. But, Bill can write a custom tow tune for that weight too.

I think Bill's shifts were firmer than the canned tunes at WOT or near WOT. Beyond that, and the additional increase in fuel economy, I can't say I noticed anything.

That's what I figured about the timing...I'll give it a shot. I plan on getting the tow tune along with the other tunes very soon.

The throttle lag is almost not even noticeable after the custom tunes.I was impressed with the canned tunes also and then when Bill tunes arrived and I downloaded them,It was like I put another programmer on it all over again.And Bill tranny shifting is the very best.I have never been in love with the way a tranny shifted like I have been with Bills tuning of it.With my stock size Mud terrains on the stock heavy steel rims,I can peg the throttle from a dead stop and burn the hell out of the tires on dry pavement and thats Both tires(aka limited slip)Its awesome.When I go to the sand dunes ,I run the 93 octane peformance and its even better.I hated the way mine drove stock.
