I've been looking at getting a tuner for awhile now, I'm finally going to pull the trigger. Here's what I'm looking for.

1. Something that reads factory trouble codes.
2. The ability to re-progam the 6R80 transmission.

I'm not looking into performance that much, altough a little more ponies wouldn't hurt. Being able to reprogram the trans is probably the most important thing to me. I've finally getting tired of all the 6R80 quirks. I would like a firmer shift and the ability to disable the 6th gear over drive when towing.

Any recommendations would be great.

I also have a 2014 Expedition with 5.4 and 6R80, so if there's something out there that can handle both vehicles that would be great too.
