Turbo gas engine have to run a lower air/fuel ratio so they don't destroy them selves. Your typical lowest N/A gas motor air/fuel ratio is between 12.5:1 to 13.2:1. A turbo charged gas engine can hit 10:1 or 11:1 during normal operation under demand for more power and there are several reasons this must happen.

Diesels are totally different and do not have to come any where close to gas engine air/fuel ratios for any reason.
