I got a chance to do a miles per gallon on my TPI today. I filled my tank yesterday and went for a drive today. 80% highway 20% street. 12.75 MPG /forums/images/graemlins/peace.gif It could be better but I laid down the hammer some while on the street and a little on the highway too. It is alot better then the 8-10 mpg I used to get with my carb.
