You're wrong John, you just don't know enough about TDI tuning to make the statements you are doing.
This is the set-up of a guy on tdiclub running circa.230 BHP with a PD150 turbo:
Another guy has:
VNT 17VB,@24psi ,,R520s,ported head,11mm pump,arp,headstuds,eurojet smic,id parts upgraded pipes,SBC stage 3, pd150 manifold, custom silicone t.i.p 2.5"downpipe and cat delete,racepipe,sender mod,pd lift pump
and is pushing 200 BHP
This is not based on generous dyno figures, but serious tuning and great custom remaps.
Btw: I said uprated SMIC, because AHF engines, etc, have SMIC as standard.

Nearly finished with my AHF rebuild:
PP764s
FMIC
Mapping
PD150 intake
Ported head
.5mm oversize valves (titanium, undercut)
3 angle valve seats
2.0l Pistons
H beam rods
PD130 oil cooler
block girdle
All bolts / studs ARP
Eur 6,000 spent on engine internals
+ a couple more thousand euros on "addons"
should be good (and very safe) for 230+ hp / 450nm
