Boston Bob's motor was getting 18+ I believe he mentioned.............who
stated 15 mph?  That motor is a stock FI system, why would it burn more
fuel?   Boston Bob made it "breathe" better by increasing valve
size.........thus it appeared to have a serious gain in HP and torque over
the stock motor .

  A fair comparison is a 2 liter type 4 engine in a bus vs. a 2 liter engine
in a Porshe 914...Both type 4 engines, both look the same except the Porsche
engine has much better heads leading to the HP gains...................
