Rick E. (Dallas, TX, US) I drive a 2019 2500 silverado it is a work and personal vehicle, I recently purchased the 6400 and 6500 fuel system kit before our tip to California visiting family. I run the 6400 through a week before our trip and the 6500 with every fill up,I could tell the difference in throttle response especially up hill on the 6%grades, less down shifting and regens averaged 23 to 25 MPG easily highly recommend it.
