Need A Little Help

[F350VROOM]

I recently had an ATS Aurora 3K installed and now when the truck goes to shift into 3rd and the engine revs real high and wont go into gear, if i let off the gas pedal it will go into gear. If I go slow 1st and into 3rd it shifts ok. Any help is greatly appreciated.

Edge tunes may have damaged the trans..did it defuel between shifts or was it shifting hard before?

I've been running the edge for over 3 years with no problems, the shifting problem didn't start until the new turbo was installed.
