HPTuners rules! I have an old HTIII for my old vortec. It was pretty good for it's day.

I've been looking for a cheap HPPIII just to recalibrate my speedo after the gear change and set the cooling fans to come on earlier. However, I have also heard that its not a good tuning device overall.
The ones for the trucks are excellent, especially the Diesels. Shouldn't give you a problem, I think the LS1 is just to touchy to program with a pre-set handheld tuner.
