So if I put the egr delete plates on my 5.7 without turning it off with the predator programer will it hurt the engine.

No, you'll just have the check engine light on all the time. That in and of itself isn't an issue unless you have some other problem down the road that you may not become aware of because the check engine light is already on.
Not all Predators have the option of turning off the EGR. It's illegal to mess with emissions and Diablo had to pull the EGR and O2 sensor options out of their tunes. Older versions may still have these options though. The good news is, if you get a Diablosport tuner, you could send a request via the Diablo forums that the EGR be turned off in a custom tune. Anyway, a tuner would really wake your Hemi up.......It's a good investment either way.
