ICP/IPR questions

I have an 07 350 PSD with 246k KILOMETERS on it. currently running a towing tune that adds 65hp on my livewire TCS tuner. Head gaskets done, arp studs, egr delete, upgrade fuel 'pressure spring, coolant filter afe intake, 8 new injectors. that's about it for under the hood.

My question is on my tuner, I can see my actual ICP. not sure how to read desired? if I can on my livewire?? and I cant seem to find IPR duty cycle on the tuner, however it does read ICP duty cycle...is this the same thing? the numbers for ICP duty cycle seem awfully close to what I have read on other threads...but not in a %. I see .23 at idle at about 580-600psi for my actual ICP. that is at operating temp. at WOT I have seen ICP actual at 4200psi and ICP duty cycle about .76

SO I guess my main question is....am I seeing actual ICP readings or desired? and is this ICP duty cycle as a decimal the same thing as reading IPR duty cycle as a percentage? numbers seem awfully similar....

thanks guys any feedback is appreciated!

OP. What you are seeing is correct. .76 is the same as 76%. Just my best guess, but you probably do not have the ability to select desired values. Some boxes are better than others for monitoring.
