I was getting ~22mpg before I rebuilt my head, which was burning oil through the valve-stem seals. When i got it apart there was a ton of carbon deposited on the valve faces as well as the pistons, all of which I cleaned up. My first road trip since the rebuild will be next weekend so I'll update after that - I'm hoping for ~28mpg. That's with stock turbo, cyclone manifold, 3G MAF, FIC 650s, Keydiver Chip, EvoIII 5th gear, 235/40/R17 tires, cruising about 80mph.
