Is Engine brake safe to use for engine?

If I’m in a pinch I drop to second stage to be safe. I also programmed a .7 second delay in the Engine break which makes it easy to upshift without turning them off.
Maybe someone can chime in, but is there some parameters I can change in calteerm to bring the boost level down a bit during engine breaking? I know reading through older threads Unilevers mentioned no more than 35 psi.

Running Rough programmed mine, the boost wasn’t right on the first go too low the second go made it too high but I didn’t really drive it and find out for a week and after that Running Rough has been busy and we couldn’t get linked up so Rawze was nice enough to let me send it to him and he fixed a few things he said the boost settings were for a Square Nose Truck like a Pete or KW or really anything without Air restrictions like the ProStar and Everyone knows Rawze is a Prostar Wizard so he found & fixed it right away I put it back in the truck and did a short test drive and it seemed to have fixed all issues with the boost I’ll know more Monday when I load up. So I’m not sure if your truck is like mine and that’s your issue but I know for the isx15 cm2350 32psi should be max boost when driving so I’d think on the jakes it would be the same but I can’t say for sure. With that said when mine was boosting 35psi on stage 3 I didn’t use stage 3 just stage 2 but the max boost wasn’t the only thing mine was doing mine was a Violent ramp from 0-35psi in a few seconds so I had to always ease on the Throttle.
