[s-cars] Mileage with MTM 1+

[Ben Swann]

What injectors are you running and at what fuel pressure?

When set correctly this and a few other chips will run: slightly rich at startup and
idle ; Stoich to lean at moderate cruise,  Accel will be slightly rich of Stoich. And
Full load approaching 12:1 A/F.  

Typical injector setup might be 42 lb/hr greentops with 53 psi pressure - that would
tend to run on the more fuel wasteful side of things, but give good overall power.

This might be what is happening.

With less injector more pressure  say 36 lb/hr @  56 PSI  fuel pressure you can get
better economy.  Best to dial in with Adjustable FPR and WB02 meter.
