Did you guys clean your MAF sensor before install? That could have might have been all you needed to do.

It seems as though not all cars are effected. But the ones that are need this fix.
Basically there is surging and a lack of power because the computer leans out the air/fuel mixture which is really detrimental to the life of the motor. Even if you don't have surging, your car might be running too lean.
Others have tried cleaning and replacing the MAF and still had issues. It's not the car, it's the design of the AFE intake.
