I tried running lean with my 85 Chrysler Laser turbo by programming the computer to ignore O2 feedback and run lean under light cruising conditions. I have a LC-1 wideband readout. It would only function as low as 17:1 and anything leaner would cause misfire. I did however get best fuel economy running 16:1 at idle at hot idle and light cruise until +2 psi manifold pressure where it descends to 11.5:1 all the way to 19psi of boost.

I always wonder why this engine won't run lean like the rest of your guys engines.
