Looking for 6 speed allison calibration file

First off,
I have been on site a long time, but my last was hacked, so i have changed username, everything. This might not be the place to ask this question, so please excuse me if its not.

I am building a truck, ITS a 2015 FREIGHTLINER S2G CHASSIS it originally had a gm 8.0 engine (that blew up ! those seem not to hold together well ) Now i have a 2009 8.1l bbc that i have put in there and it runs fine, great fit. My problem is i am trying to retain the 2015 Allison 6 speed. the truck i took the 8.1l out of had a Allison 6 speed but it was from 2009, i am told the program in the Allison computer is different even though they are both 6 speeds. So what i need ais a 2012 , 13, 14 ,15 allison calibration file, i can adjust shift points etc. just need the base file maybe out of a 12-15 Duramax truck anybody got one. thanks in advance.

( moved to Diesel->Allison 5 & 6 Speed )
