Well, I installed my Unichip on Friday. Installation is tight, but the Unichip wire looms are plenty long. The problem comes from the factory wiring looms being so short. I took the fuse box lid off and unbolted the fuse box too. Additionally, I unbolted the wiring bracket that holds the factory wire on the top of the computer and bent it towards the computer to give me a little more play in the wire. I left the back bolt out of the fuse box (just no way to get it in) but put the other two back in. Truck seems to run smoother (I just have a catback) and power seems to be a little more.
Drove from Casper, WY to Billings, MT (275 miles) on the interstate at 76 to 77 mph by gps and averaged 20.0 mpg calculated at the pump. My previous best on this trip was 19.0 mpg so this is promising. I picked up a 21 foot toy hauler and towed back to Casper on Sunday. Tundra towed fine and I didn't have any problems. This is the first trailer I have towed with the Tundra so I can't compare before and after towing, but the Tundra handled the trailer pretty well.

Maybe after some #'s and a version 2.0 with longer looms I'd pull the trigger.
