[200q20v] soft boost?

[Beer, Jerald]

  Just for grins, I disconnected the WGFV. Interestingly, the car will only
pull about 10psi, and is sluggish to get there. Normally pulls 21-22 peak,
15-16 @ 6,000). Feels like the old TBV hose is cracked, which it is
not(visual inspection, behind heat shield too). Car has k24/26 from 2B,
older IA3 chip, 2.5 PT and T-P WG spring. Car reads 18in Hg at warm idle so
I don't think vacuum leak. No apparent boost leak (no sound, MM hose one
year old, lower intercooler hose replaced 6 months ago, recent Bosch 108 TBV
installed). Is this an anomoly because of the slightly bigger turbo, or is
there something wrong? BTW, no codes showing up. TIA
