Ren,
The tunes are the same in the programmer as the chip. However, the tunes that come with the programmer are factory Edge tunes. So, you want to order 3 of Bill's tunes to download. I originally was running the 65Tow, 80Performance and Fuel Sipper. Now, I have 65VeggieTow, 80Diesel and 80Veggie. (I run my Ex on filtered waste veg oil.)
I was having fun with the stock tunes, then when I downloaded Bill's tunes, I was REALLY much happier. More power, better shifting, better fuel economy.
My Ex got about 12.5 mpg when it was stock. I did the Tymar/Zoodad and 4" exhaust and that went up a couple mpg. Then, I installed the Vegistroke and veg oil does a little lower mpg than diesel. Then, I got the Gryphon and they went up a lot... then even more on the custom tunes. So, right now, on veg I average 16 mpg town / 18-19 mpg highway on veg. (And I slam it all the time, just to smoke it up and toss the Ex around.) On diesel that should be 2 mpg higher - and I believe pickups get better mileage than Excursions. So, if you're burning D2 in a pickup with the same mods as me, I guess you should be averaging 18-20 mpg around town and 20-22 mpg highway.
Talk to Bill about the power levels, but I decided to stick with the 80 because longevity on my motor/tranny was the most important thing to me. I don't know if that's valid thinking, but that's where I'm at for now. I admit, I am curious about the 100/120 HP tunes though... maybe someday, I'll do more with my motor (injectors, head studs, big oil, turbo, and hotter tuning), but for now, I'm good.
FYI - last time I ran my 0-60 time on the 80 tune (with 40 gallons of veg and 10 gallons of diesel and three passengers), it was 7.2 seconds. Don't really know how that compares to other folks, but I'm pretty happy for an 8,000 lb truck.
