Don't take my word for it, I'm sure other members will also post their opinions about altering the computer programs for modern automobiles. Pro or con, the decision is up to you. If you have a warranty on your vehicle, contact Chrysler and ask the specific question: "If I add a performance chip to my vehicle, will it affect my warranty?" The answer to that question should help you decide on what to do.

As for flushing the transmission and changing the filter, that is regular maintenance. Follow the "heavy duty use" recommendations for your truck, found in your owner's manual. Any unique problems may alter that maintenance regimen, but Chrysler's maintenance regimen is usually adequate for any vehicle that isn't "abused" beyond its capability.
