Some updates:

1) Replaced the throttle bodies with brand new ones
2) Moved the MAFs closer to the throttlebodies (revised piping)

Advice new style Stillen S.C. Intercooler pipe (MAFs at TB)

3) netted 25 extra wHP with AFR 10.5.
4) GODDAM p0300 is back. Tune shop states that the Z is trying to hit an idle target of 700, it bounces at around 780, then cel comes on. Went through the idle relearn several times

The voltage on the throttle bodies were checked and what would be the drivers side, which has the T.B. extension, is seeing lower voltages than the passenger side w/o the extension. If the passenger side is .80, then the driver's side with Extension is .74.

I am going bananas over this. So possible that TB extension is an issue?
