Resolved 2G Bogs during partial throttle/boost

[Mike_GST]

I'm having the same exact thing for a long time. WOT car pulls damn fine. If i'm partial throttle and then build acceleration slowly up to WOT it bogs bad, even with turbo spooling normal. In this same bogging episode, If I just release the accelerator and go straight WOT, the car reacts full performance again.

Replaced plugs with NGK BPR6es and checked the gap, replaced spark plug wires, checked coils (primary and secundary resistance), checked power transistor, replaced BOV (recirculating), replaced fuel filter, cleaned and tested fuel injectors, air filter is fine, PCV valve is fine and no boost leaks.

A bad throttle position sensor would result this bogging pattern?

EDIT 1: compression test all cylinders between 170 and 180 psi.
EDIT 2: no Check Engine Light, never ever.

After two years studying, testing, cleaning and replacing things in my cars engine, I fixed it giving a real bad tight on the alternators belt.
My episodes of bogging happened when I hit the throttle the exact same moment the AC compressor was comming in. It's something that you can't notice without a voltmeter, but I got suspicious after using my car for a month with the AC off.
With the belt slipping during a high torque output, alternator wasn't keeping a stable voltage supplying AC clutch, electronics and ignition.
