Which Chip for a 5.9 Cummins

[txaggie90]

Hey Green Screen.... Just replaced injectors on my 2003 Dodge 5.9 Cummins.
Bought this truck new and always have gotten 20-22mpg on the highway 14mpg pulling trailer. With new injectors have lost 3to 4 mpg across board.

Have plenty of power but interested in fuel economy since I travel a lot.

Any suggestions.

Thanks

Whatever chip you choose you better make your mind up quick...heard the EPA is in the process of outlawing their sale.

*edit* apparently only the ones labeled for "off road use"

Our decision to discontinue these products is based on recent statements made by the United States Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) regarding diesel performance products intended solely for racing/off-road use. The EPA and CARB have taken the position that the manufacturer of such products is solely responsible for the proper use of those products by the end-user. Despite our best efforts to carefully develop and implement procedures designed to ensure that each purchaser of our off-road/race-only products is aware of his or her legal obligations and promises to use those products in a lawful manner, as of this time we have not been able to gain satisfactory assurance that such measures will be considered adequate by the EPA and CARB. Consequently, we have chosen to withdraw our off-road/race-only products from the marketplace until we are able to verify that the sale of those products can be achieved in a manner that satisfies EPA’s and CARB’s concerns.

We will continue to monitor developments with regard to applicable federal and state legal requirements. If and when we are able to re-introduce these products into the marketplace in a manner that definitively meets all EPA and CARB requirements, we will do so. In the meantime, we trust that you will understand the basis for our decision.


Thank you for your continued support.
