I agree with replacing the MAF as preventive maintenance, especially given its low cost and important role in protecting your engine. I had the same hesitation symptoms as you, but no pinging and no CELs, and replaced the MAF with dramatic improvement. Boost comes on smooth, early, and strong, holding steady at the edge of the red through 3d gear and up. My Viggen is stock.
You have it right about a worn MAF causing lean burn and knock because it is not accurately measuring the quantity of air going into the engine (it thinks there is less air than there really is).
This is a fun $130 maintenance item, your car will likely run so much better.
