I get 2 to 3 mpg better in comfort mode on the highyway but around town no. so if I am in town or offroad its power mode.gas mileage is better in power mode as well.
with the revamp to H.O. in 1991 chrysler removed the power/trans option and simply hardwired the trans computer to power all the time. they found that fuel mileage loss was significant in comfort mode (2 to 3 mpg) and did away with it.
Thats why I thought I would throw that out there. we have had them for years and years. might be interesting to compaire different thingsit has to be a difference in origin for sure...
we don't even have daytime running lights on anything older than 5 years for the most part
