Possible you bounced the MAF Sensor off the car? If so that could be it. Do you reach a certain RPM and it won't go any higher? Maybe around 3K? If so the car could be in Limp Mode due to a bad MAF Sensor.

How does it secure the MAF so that it does not move? The QR MAF is extreamly sensitive and will go out at the drop of a hat, one good bounce and its dead.

Nismo (and to my knowledge AEM) both use a brace to keep the MAF stationary. If your brand does not have that I recommend upgrading. The cost of the Nismo/AEM is a lot less than a new MAF.

Yep, can the ECU be reset on the QG engine to fix this problem, or is the MAF dead?

What Kind of car do you have? Depending on the motor you may be making a trip to the dealership real soon.

Probably wasn't mounted right... the CAI should have little or no movement.
