Hypertech shift points w/ 38's

[H2 Doberman]

I searched the forum and found some info on people's shift points but they did not say what size tire that they were running. What are you guys with 38 inch tires setting your shift points at. I have 38x15.50x18 with stock gears. The truck runs fine but like other people have stated, at highway speeds it will shift out of overdrive alot. Anyone have any good advice on the programmer. I have the shift firmness set to 50%. I think I might try 100% and see how that works.

The hypertech lets you adjust shift points? Cool, might have to pick one up....what else can it do?

How do you like that Hypertech module anyway? Do they work well? I'm not sure which kind to buy. I had a Hypertech on a Bronco when they first came out and it didn't do **** for the performance or anything else. That was in the days when u just plugged the thing in and it did what it wanted. There were no adjustments that could be made.
