15 minutes is pretty standard for letting the ECU reset itself.

Didn't you find an SVT MAF?? After we put are SVT MAF on, the car runs better. He still has the stock MAF but isn't willing to part with it yet.

Be careful when unplugging the MAF and jump to the conclusion that it's the MAF that is the problem. If your getting unmetered air into the engine, from say a vacuum leak or before the throttle if it isn't on properly, air can sneak in at these points and it won't be read by the mass air meter. When you unplus the MAF, the ECU detects that and goes into a back up program and could mask the unmetered air and give you the results of your car working properly.

Where the air flows through the MAF, the air filter (oiled) can screw up the readings your MAF is getting. Try cleaning the wire sensors in your MAf with throttle body cleaner.

Before this happened had you just cleaned your air filter?
