'06 RAM 5.7L - Poor Gas Mileage 93 Octane (9r12)

[Agimax]

After upgrading to the new 9r12 software, i have been on the unmodified 93 Canned Tune w/ perf Trans for weeks now and noticed a substantial drop in fuel economy, yes i have been driiving it like a grandma trying to squeeze every mile out. the best i can do is 15.5 now and before i got 16.5 - 17 almost daily and could squeeze 18.9 driving grandma-ish. No i don't used the new 'Mileage' Tune cause i always use 93 Octane fuel. I used to be on the 9r09 before the upgrade (i tried the 9t12a/b also before the released version) and stayed on the 93 Canned Tune most of the time. Could the new MDS Smoothing done in the canned tunes the issue?

The Mileage tune isn't built for power. On the 9r09 i was getting power and mileage, just was trying to figure out why the worse mileage with the new 93 canned tune now. The tune runs great, just bad mileage. Do you have any ideas on what could be causing this in the Canned Tunes?
