2004 Burb 8.1 Shifts_TCC.ctz

Just for the heck of it, give this a try and see if the TCC acts different.

I searched all my tunes and i don't see that OS. I know on the larger trucks with the 8.1L there are several tables that we cant get to.
On a friends Kodiak with a 8.1L the Throttle wouldn't go over 50% over a certain speed. Ended up finding the original guy that did the calibrations on those trucks for GM and sure enough after changing some stuff to the 2500HD Truck tunes it made all the difference.
