Re: 250 i6 fuel economy w/o sacrificing HP

Never thought to ask is the 15 MPG in town or highway? if your going into 5th gear on the highway with the OD .73:1 gear your going to throttle harder than if you kept it in 4th with the straight drive 1:1 gear. If it is in town... Get a proper tune on the carb jetting and ignition timing, and stay out of the throttle...
