I'm thinking of getting a programmer anyway, but I don't know where to start. Do they really make that much difference? </div></BLOCKQUOTE>
hi Rox. yes the programmers wake the truck up! I have had Hypetech III's on my last four trucks! I love them and ca't wait until they make one for my H3.
35's on 18" are very nice looking and functional. Although must of us ha 37's in Moab last time, 35's went over everythingthe 37's did. 35's IMO woul dbe best with your trailer too. But get the programmer too. </div></BLOCKQUOTE>
Thanks Tim! I'm working on it as I type. I'm anxious to see how well they work. The 05's have been re-programmed from the factory, and it seems like they just changed the shift points to an even higher RPM. My 03 Hummer had 50k miles on it and second gear was starting to slip. When towing with the H2 over uneven terrain, meaning hills and passes, it spends most of it's time in second gear. It's programmed to shift out of second at around 5000 rpm's (can't remember the exact #(75miles per hour). It pulls the grade, but it's the darn tranny that takes all the abuse. Hopefully a program that makes the torque converter shift harder will help so I don't go thru some of the same problems with this H2 that I did with the last one. I've haven't quite given into the idea of slowing down, yet.
Every state but Oregon has a higher speed limit, so it's nice to be able to keep up with everyone on the highway.
Hummer really should put a bigger engine in these things, or at least offer it as an option.
Technically, I should be driving the Excursion all over Creation, but that wouldn't be near as much fun!
No one will flip me off in that!
