These motors were designed to run lean. You have the correct map for you setup. Run it some more and check them again. Dispite all the screaming about the 07 running hot and lean (which they do) doesn't seem to be any failures related toit. Chances are good your running richer than it did out of the crate.
An old gearheadmoto "Give the motor what it want" If its running great I think you've done just that.

RE: running lean
First off... A 5 minute ride isn't going to tell you squat...
I have said it before, and I keep saying it.... YOU CANNOT TELL IF IT IS FAT OR LEAN BY READING THE PLUGS......
You need to use an o2 Meter.... That is the only true accurate way to read what your Exhaust gas' are comprised of and how they are mixed.....
Take your pc out with you, and record o2 Data Mode.... You will see what the o2 Integrators are doing, to tell you if it is dire need of tuning...

Or you could tune it right with a dyno so you really know whatis going on. Its kind of an expensive part to be playing a guessing game with. THE MAPS THEY PROVIDE ARE JUST AN EXPENSIVE DOWNLOAD. IF YOU WANT A CUSTOM INTAKE,EXHAUST AND OR MOTOR WORK
!!!!!!!!!!!!!!!!!YOU NEED A CUSTOM MAP!!!!!!!!!!!!!!!!!!NO GUESSING
