Wowzers, I really am glad I got the HPPIII. It was worth every penny $310 or so, especially if you are running 31" or taller tires. I got it all programed. I got it set for 93 octane, 31" tires, 3.73 ratio (set it just for good measure), changed shift points: 1-2 (normal), 2-3 (-3), 3-4 (minus8), and for sift firmness. I think I covered it all. It's like so awsome. I have no desire for gear changes now. I changed 2-3 shift cause it was going into the dotted redline. 1-2 was perfect shift stock, and 3-4 was changed so I would hold 4th on slight hills on the highway. I'll never do WOT 3-4 shift anyhow. Oh, I set it for 110mph limit and 5800rpm limit (although I should lower it), I never want to do more than that! LOL. The nobbies would probably fling off the tire! lol
My engine dows feel peppier and better mileage, unless that was from the speedo calibration for tires, dunno, feel way more better overall, feels like a different truck. I may try -10 on the 3-4 shift, but that may be too low, dunno.
I am very happy to say the least. And I feel I have saved money, cause I don't feel I have to re-gear now! Yehaaaawwww!
