2005 LLY 6” lift, 4” cat back, PPE down pipe, AFE mouthpiece, Cold intake, FASS fuel, Amsoil Bipass
I had my truck tuned back about 11 years ago. My 2005 LLy has been a good truck. But over the years driving and shifting has changed. I had my truck programmed by a tuner in Las Vegas. I’m not sure if he is still around and I don’t have his contact info. He told me I was paying for a license And custom tune. How do I get it checked and updated. If I take it to a shop will they be able to see who did the tune and see that I already did EFI Live or will I have to start over which I don’t want to do. Thanks in advance. Any recommendations appreciate.
