Hypothetically, would it be possible to tune a car to get better milage than what it came with from the factory? Lower the boost, take out some fuel?

After hacking the MAF properly your fuel trims should be close to their normal levels. If I had the guess they would end up at 125lo 110mid 100hi. This is commonly what happends when you hack a maf because at low air volume, such as idle, most of the air goes through the hacked section, but from cruise to WOT the flow evens back out. This is why you hack to get the high trim between 100 and 110.
