Also, my truck lags and I've almost been in 3 accidents because of it. You think you have time to make a turn, and you don't because the truck won't accellerate much when it is cold. It never had this problem until after the AEM.
How do you get the "updated AEM that the U.S. Environmental Protection Agency and the California Air Resources Board approved in December" that is mentioned in the FCA letter. Does anyone know?
