Okay ONE more pcm tuning question!
Why I ask is because I'm unsure if I will have to go through and make sure it reads the correct gears (stock but 323 option) and the correct wheel size (17 inch).
How does it know what I have if I don't enter the data in?
Does it just keep those things from the original stock tune on the car and only alters things like a/f and TM etc?
*I just want to make sure that it doesn't default to 273 gears or something like that. I'm hoping that it just takes that info from the stock tune and incorporates it into the predator tune and is then uploaded to the car.
