I have to admit that this is all very disconcerting.

My 2.5 only has a better air filter and 3" dump pipe with OEM cat back zorst and with 213 HP ATH with well over "15.5 PSI" (VERSO by ASG)

How MMS got your 2.5 to 213 KW ATW with only 15.5 PSI regardless of the mods is a question I would be asking. I'd suggest it had a lot more boost than you've been informed / quoting.
