So I bought a 2011 Taurus SHO, with 88k miles on it 15k out the door. On the test drive I knew the car had a minor issue or two, but I worked those into the We OWE , so the dealer would fix. Being a ford, I got the ESP for it.
I get it home, its not performing or quite running like it should, I hook up torque, and see its running boost, at levels that say its tuned. I go back to the dealer and ask the service department to check to confirm and if so to flash it to stock. ( I don't want to run someone elses mods not knowing whats there) And I was told, they cant flash it back, because its running aftermarket sensors, and a few other mods and that it is indeed tuned. The guy knew this without checking the car.
So obviously the dealership had knowledge. I NEVER buy modded cars, I don't trust them, and I know usually they've been driven hard. Had I of known I never would have bought the car.
I also noticed a number of other issues, The Oil pressure light has come on twice, and the transmission slams gears. I bought a Tuned, lemon. And im not even sure that the warranty is valid because its tuned.
Basically, im stuck with a car running a tune I know nothing about. the only two choices are buy a $400 tuner and have it retuned, or Spending ~300 to have it put back to stock.
