EFI install on my 360

Can you explain how you are routing your fuel lines. From tank to pump to what first?
Where is your return plumbed into the system? If you have the fuel pump hitting the regulator first you are asking for problems. Guys have burnt up pistons like that with EFI. You may have it like that. I can't tell in the pictures.

The Fuel Rails should be tied together as a U with fuel coming in the beginning of the U from the Pump and the return on the end of that U so the Fuel Pressure is full tilt boogie at the injectors and bleeding off after hitting all of them.

Intake air temps in the Air filter...... Shouldn't it be after the butterfly's down on the intake or on an aluminum spacer under the throttle body? I think you are going to get false readings like that.
