Oh yeah and the same mods too, like the intake for example. The tunes must be for the intake you're planning on using, if it's an intake that requires a tune to run.

 

Sorry for the confusion, I myself am confused lol. I am using my OWN tunes, not his. So, would this work:

Delete EVERYTHING from the Xcal. Order my tune for MY Car with my specs. Backup the stock tune on the Xcal, and upload my new tune?

 

That is probably the safest option, at least that way you can be 100% certain that the tunes are built for your setup and you won't run the risk of damaging anything.....
