Not sure which 1999 Dodge Ram Performance Chips & Programmers are right for you? We have over 675 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. John M from Mountain View, AR said, "Very easy to install Stage 1 module (10 min) after closely reading the directions. Remove your truck's computer (three screws on firewall) & press module into place on a workbench. Do not try to press it in with the computer still on the firewall. You won't be able to get enough oomph. No mileage check yet. I like the module well enough....engine runs smoother and doesn't always have to shift down going up a small hill towing a 25 ft RV. A good value for the money."
