Here is a Performance Chip from "ROCKET" for the 2018 to 2022 RAM 5.7L Hemi. I had this on my last lease truck. It works well and does indeed help the performance of the truck over the standard factory tune. This is a simple Plug-in unit that can be installed and removed without tools in a matter of seconds. I have the installation instructions and will offer to install it for you if you wish. Here is what Rocket says it will do for you:
– UP TO +60 MORE HORSEPOWER
– UP TO 25% MORE TORQUE
– UP TO +4-6 MORE MPGS
• Increase Vehicle Mileage
