Who has the best tune?
I want to order a JLT Intake & tune for my car, my question is which vendor has the most power making tune? I was thinking of ordering from JLT, or Evo Perform, but I want to get the one with the best tune.
Also later I want to add an upper and lower pulley, how do I go about getting the new tune for that later on when I want to add those?
Thanks for the help!
