4327, RE: Daily Driving Near Stock MS Posted by ner947, Dec-31-69 06:00 PM
I had a daily driver with the MS, hooked to a wideband and if you tune it leaner than 14.7:1 in vacuum, 30+ MPG is easily obtained. If I drove very conservatively I would get around 35 MPG. If you do everything right, the car runs far better than with the stock ECU.
