Anyway, finding out what the difference is between the 07s and 08s is pretty much just out of curiosity at this point since it looks like the GM tune will be released for all model years.

Knowing that when the 08's were released there were no posted Engine Changes, it must be something they changed due to a supplier change/part change/mix change. But the 08's were advertised with the same core engine and numbers. I too am curious to what the changes would have been. I am sure they are "please ignore the man behind the curtain" type changes.
But as you said, they did say all model years, so at least we all have the opportunity to partake in the new offerings.
I know this is mod sacreligious talk, but I hope they keep a little held in reserve so that it does not severely effect the life of the engine.
