limp mode. I had suspected MAF problems before. I cleared the codes and I disconnected the MAF to see if i would get a check engine light again.
So after driving a bit its come back again, although i havnt pulled the code up yet. But boost is back at least.

So is driving around w/ the MAF sensor disconnected bad?

Default what year is your car?
no, driving around with an unplugged MAF will force the car to use base values for air/fuel. So consider it a fail-safe. It should be fine.

it won't hurt it. Keeping it in chipped mode will force the engine to try and meet conditions it's not suited to with a malfunctioning MAF.

Replace the MAF and at the same time put in new plugs
