Wife wants a tune!
Fellas, I think I made it. My wife said she wants a tune/chip for her X5d. I have a 2012 335i with JB4 on it and she loves the way it rides/sounds and she wants a tune for her diesel now. She has a 2012 X5d that is bone stock. I know tunes for diesel trucks really puts out some numbers and was wondering if the X5d will as well? Also, what is the popular tune and safest route to go?
