double check its installed properly. try disconnecting the battery for 30 seconds and then reconnect. the vehicle may just have to relearn adaptive strategies.

also, not trying to be mean when i say this, but i see you posted this thread 3 times. in the future, one time will suffice. a moderator in this section will merge these threads as to not make things confusing.

What size is the venturi where the MAF is? I've seen Spectres with a 3 inch throat and i believe stock is 2 1/2 inches. The extra area allows more air mass to flow for a given velocity (which is what the MAF sees), resulting in a lean condition unless you get a tune to calibrate the MAF for the larger area.
