This^^Just don't ADD Up Does your Boost gauge Read 0 at KOEO??
I wonder if he has a Bad Map Gauge???
I think MAP is Preset INTO Scan Gauge Already so it shouldn't be a Code entry thing
I do have a MAP Volts gauge I can Give him maybe we should check into that Reading

ipr=14.84 lo-24 hi-40.60
flp=12.0 lo-13.5 hi-13.5
fmp=48 lo-48-hi-48
vgt=0 lo-73 hi-43
egr=0.8 lo-0.8-1.0 hi-1.3 egr valve position
egrdc=0 lo-0-15 hi-32 egr duty cycle
ebp=15 lo-16 hi-16
bst=epd 3.26 lo-2.43 hi-2.13 ep exhaust pressure desired
vref=4.9 lo 4.9 hi 4.9
some of these numbers don't and wont match the same but should be close testing values. my concern is ICPV ,map hi at 38, check EBP tap and ICP connection wiggle test . sorry guys for the long post

From my notes,
P2262 MAP Turbo/Super Charger Boost Pressure Not Detected — Mechanical CAC system leaks, MAP hose disconnected, exhaust system leaks, intake system leaks

Did the boost read 10+?
You know MAP - Baro = vacuum/boost right?
