Thanks again to Tom for his help with my tune.
I have the SCT Pro Racer Package, and it was great to see how Tom tunes first-hand.
I approve 100% of how he does his tuning, and would recommend him to anyone.

Now, as for my 3" MAF issue: I could only get it to work properly when I used the stock air straightener and tuned it open loop.
For whatever reason it will not run well when attempting to use both the MAF and STFT.
Now it's running quite well and making more power than ever.

The reason I couldn't get a good reading from the 3" MAF was due to my pipe configuration.
Even though I had 10"+ of straight 3" pipe before the MAF there was a 2.5" 90* bend before that which opens up to the 3" pipe.
My BOV is mounted in that 90* bend, which also causes turbulence.

If I removed the MAF from the bend and ran it open it would idle and rev fine.
As soon as I put the MAF back the idle went erratic and the car would stumble like crazy.
The air straighter helped considerably, but still wasn't enough until I tuned it in open loop.

Bend:

Your to close to that turn , Rotate the pipe (cut out the 3 inch) and move the MAF electronics to the center of the 3 inch and try that

The newer slim MAF is much more sensitive about placement , I also feel with moving it you will have better driveability and transition
