Performance Programmer Tuner | 40490

Not as good as the tune that I had on it when I purchased the truck. Unfortunately, I had some mechanical issues and the mechanic put it back to stock. I used to have more power and it was more Driver friendly. Used to be when I stepped on It that it would immediately launch no matter what speed I was going. Now it has to spool up and then it goes. Also, it used to downshift sooner when starting to pull a hill. Now I have to get my foot into it more and more and then finally it takes off hard. Which that uses a bit more fuel. They told me to drive it for 10 days and see how it does. No difference. I expected to be able to speak to someone doing the programming, but it’s only been communication through email. It’s better than stock, but I am not as pleased as I had hoped. Ugh.
