I honestly have no idea. Other than the vacuum line to the BOV and removing the intercooler, literally no other air-carrying lines were even touched... A theory I have is maybe the MAF signal disparity was initially manageable but the addition of the 9lb pulley caused the imbalance to be too big? Maybe?

Even that I could argue you should see problems immediately following the install...

The other theory is that maybe the orientation of the coupling from the intercooler to the intake Y pipe is directing flow differently after removing and replacing the intercooler.
