Glen,
	Are these numbers from the trip computer? Have you verified them
independently by dividing the trip odometer reading by the fuel filled?
I get similar numbers, though slightly less, on my '87 5KTQ on the
trip computer. But the actual mileage computed is a good  15% less.
That trip computer mileage reading is not to be believed unless 
independently verified. I believe there is a calibration switch for the
trip computer mileage, but I haven't adjusted that yet.

My mileage has dropped somewhat after I got the IA Stage II mod, but that is
to be expected when I'm accelerating like crazy at 1.8 bar boost!
