I just installed the xcal 2 on my 07 and I have the jlt ready to install. my question is....is there a certain tune setting that needs to be in place when installing the jlt. Do I have to add a custom tune just for this intake or can I just install it with my car already being tuned. I am tuned for 87 now, but will soon try out the 93 tune.
