Assumingly both should be lower than stock from what y'all are telling me.

i haven't checked yet. i drove the car to the ppf shop this morning and dropped it off. i'll pick it up tomorrow mid-morning and perhaps see what numbers the car is giving me through the infotainment screen as well as through the jb4 app. i don't have an obdii reader other than some cheap wireless unit that i only use to connect bimmercode with. although, yeah, clearly the car is going to tell you that the boost is lower than what it actually is because that's how the jb4 unit works... the jb4 unit is doing the fuel:air ratio thinking while the car is fooled into lower than actual figures. of course the jb4 has a failsafe threshold built in so you don't ruin your engine.
butt dyno is strong, for sure.
