Well, I reinstalled my TB spacer the other day. All I have to say is "holy crap". I filled up my tank here in town and I drove over 200 kms at 130km/hr. Then I put $5 of gas in (6.5 L into a 65 L tank) and drove home at 95 km/hr. My odometer is now near 450kms. If it gets over 480 kms that will give me a around 12 L/100kms. Converting that for our less enlightened friends to the South, that is around 20 mi/gal. Way better than it has ever gotten. The best I have gotten before was 14 L/100kms.
