Evo 9 Bogging / Hesitation under Boost
My Evo 9 with 118k miles bogs under boost.

The dealer replaced the spark plugs and "updated" the ECU per recall. The dealer supposedly tested it after replacing the plugs and the update and stated it was "good/done."

It is still doing it under heavy acceleration / boost. It does it most violently in 5th gear going about 70MPH.

Any ideas?
