Thanks Greg. I actually do work at a GM dealer and can get the updated PROM for a good price. I would not like having the 1-4 skip-shift feature back though.
What I am considering is going with a Haibeck chip. Theirs seem to be researched pretty thoroughly and I have read some favorable comments regarding how they perform.
One thing I really dislike about this one is how the idle constantly "searches" as I am coasting down in gear. It makes it feel like the engine is surging. Once I'm stopped the idle goes up and down for a couple of seconds then settles in. Very annoying.

Meanwhile... the learning continues.
