So prior to my long tubes and 4.09 gears I was running a Lunds 93 tune with no issues. I was interested in the vmp flex tune which I heard was very successful. After the installation I to pick up my car at my buddy speed shop. Who only does mustangs he was in the car with different sets of computers. He said my blind spot & cross traffic along with part of my gauge wasn't working it gave a fault code. Never had a issues before that and was with Lund they vmp 93 tune. He tried it with the Lunds and same thing happened. It only comes on when you are driving and you even get a wrench light. So he checked body modules and nothing. So I contacted lunds I also noticed my ecu strategy was no longer visible on the tuner. They said it was strange but they gave me a new tune so I can make adjustments. I was able to set the correct tire height and I also put 3.73 gears since it doesn't list 4.09. I took it for a long ride and no issues. So I returned my car to stock and loaded the vmp tune which they redid for more options. I did it the same way as lunds and the fault lights came on VMP told me to take it to the dealership it has a bad module. I said so why does lunds work fine. He was not pleased he answer why get another tune if have lunds. I said I always have 2 tunes yours was going to be my flex tune. Have not heard back from them and my other buddy has a dyno shop and works with them. He usually does my tunes hopefully they can figure it out or refund my money. I bought a flex tune from lunds since they had better answers for me. It's my 5th mustang and never had a issue before even with Bama.
