THIS IS MONEY WELL SPENT! I have been getting the same fuel mileage 16.2mpg. It is nice to know I don't have to worry about premature engine failure! I did not have oil consumption issues and I did not want to wait for them either. My engine has 35k miles. No check engine lights either so far after 1 month of use. It is a very solid piece of technology.
Great tuner really woke up my Silverado
I think the Diablo Sport Tuner is a great investment for the money,it does everything they say it will do. And the menus are easy to navigate. It really woke up my Silverado, the multiple truck use is a nice option agreat s is being able to turn off the active fuel management
