    from what i have read the GM MAF are pretty flexible at handling lots more air/colder air,if you were most likely you would throw a code that says you are running lean

    Hz maxes at 15,000. You need to tune your car for the new MAF and you also need to tune for major changes (such as adding an intercooler). The air going over the maf element is going to be a different temperature so the readings will be completely different.
