Weird ICP issue?

[BlueWaffle]

I data logged my truck to check on my ICP actual and found that at WOT, it was only reading 1600 psi. When I checked the ICP demand it was only calling for 1700ish psi. Both readings are less than half of what it should be but the truck was still pulling hard. Sound like a tune issue or should I look into a possible HPOP issue. oh and I have 190/100's and a powermax. stock ficm.

It's because of the tune or ficm that it reads low.

Pretty sure the tune. My ae reads mine out like that

the ficm is stock though?

I think it's the tune then. You need a mech gauge. It freaked me out the first time too.

just put it back to stock and it's reading 4000 psi....it's the tune. BOOM.
