I've noticed that the TH runs pig rich at cruising speeds. AFR is around 13.4 and thus is causing poor gas mileage; 16-17 mpg cruising.
My question is, how much better on cruising load gas mileage have you guys seen when optimizing the stock tune, or even full blown upgraded tunes on 93 pump to be in the 14.7-15.0 AFR range?
Any reason why Chrysler set the AFR so pig rich at cruising loads?
