Newbie, don't laugh (too much) - MPG Question?
I'm not laughing...there's nothing funny about a well tuned and efficient running engine.
My previous 460 big block Ford (400 horsepower) got 13 MPG (city) with a Commander 950,
electric fans & Lentech Strip Terminator wide-ratio AOD. Here's another good example:
(16.5 MPG with an 860HP/742TQ 555" BBC)
Fuel economy is a result of how well you can tune EFI. The base calibrations offer good starting, idling, driveability and power.
The potential for great fuel economy exists, however, you must tune your particular application to achieve it.
May God's Grace Bless You
