Anyway to determine what tune is on a truck?

I bought a 6.4 truck to replace my tired 6.0. New truck is deleted, I did a read with hpt and it read fine I know it?s deleted in the tune as drive it a little before pulling motor and it had no emissions codes. Just wondering if there?s anyway to know what they had previously used on it. I picked the truck up at the sale 8 hours away so no previous owner to locate.

if you can send me the file i can see what it is.. i couldnt tell you who its from because majority of the people that sell tunes buy them from other people that actually write them.. i can take a look at it and see what kind of tune it is as far as if its a tow, street or race file..
