7103 eco mode shifting hard on 6.0 tbo dsl

[Cjruiz19]

Just uploaded new 7103. Shifts harder than usual. Is this normal, is there an adaptation period? Does it need to be adjusted?

So I tried installing eco mode with stock shifting and it felt very weird. Had to install stock mode back until I get some type of answer from diablo.

I have had the same issue with a tune from Diablo on a 2006 6.0 and I just recently purchased a Predator 2 for my 2011 6.7 and it has the same thing. I only run the stock trans tune because it feels like the T-case is going to fall out otherwise. Completely stock trucks both times.
