#1... You have an AEM. You do not need the MAFT or the GM MAF. Hell you don't need a MAF at all! You need a 3.5 bar MAP sensor wired in and the AEM should be doing all of it's load calculations based on a speed density setup.
You need to load the proper cal file for your configuration, either speed density or maf based. If you have never tuned an AEM before, you will not get the car to run properly. An AEM needs to be tuned by someone who actually knows what they are doing.
GET RID OF THE MAFT & INSTALL A MAP SENSOR!
