I have the Hypertech PP III that has taken the tire size and gears into account to adjust the speedo. I have noticed the difference with and without the programmer but from what I'm hearing, the Hypertech can't even touch the coat tails of the Gryphon.

Should I use the canned tunes or what other tunes should I get?

I'm not Lars, but I take back what I said about the tow tune. The gearing you've got on your truck has made towing your loads easy, even with the big tires.

I think all you need is an 87 performance/economy tune. I think you'll probably see better mileage and performance compared to the Hypertech.
