I have researched this a lot and really want to do it, but I never live any where where I have access to it on a regular bases. You can run it with only change 1 table in the tune, but to maximize it you should do some tweaking to others. The fuel systems in these truck are capable of handling it.

It is harder to start in cold weather, but some tuning tweeks can help that.

Do you really think GM would use parts that fail with 85% ethanol when there going to build both systems and even the non-FF vehicles have to be able to run 10-15% ethanol? There are quite a few people that have done conversations with after market injector modifier boxes only and I haven't heard of any that have had fuel system component failure problems.

I really think there is some gains to be had especially being forced inducted with this fuel. This is something I REALLY want to do, just to do it!
