2021 F450 tuning and CP4 longevity

Will the CP4 in the 2021 6.7 support 50-100hp tune from AMDP? Will it tax it to the point of failure?
thanks,

I thought the limit was 800hp before replacing the plunger and top hats but this article says it’s 700hp.

granted a tune with out upgraded top hats and upgraded injectors won’t give you a very big wow factor.

thanks,

Most you'll see is a drop in line pressure from not being able to keep up with volume. There shouldn't be any ill effects as far as life expectancy. If you ever had a 7.3/6.0 kinda think of it like an hpop, It's a pump that moves fluid with a device that regulates flow (Ipr/mrop). If it can't keep up it will just fall on its face, granted I wouldn't constantly let it drop to nothing. But it will tell you if a tune was too much.

Edit: by the way, when you get time with amdp I'd love to hear your experience. Especially with the transmission tunes.
