Hey guys i just got the SCT XCAL2, say if i upload a tune to my car right and then later i get a mod can i use the same tune to customize it or do i have to make a new one? i hope that make sense, becuase i kno it can hold up to 3 tunes but i want to know as soon as u upload a tune, does that mean you can never make changes to them. PLEASE HELP! THANKS@!!@

 

You should call Fred at Evolution (610/485-3596) and ask them directly. Regarding your question, some mods will not affect a tune, while others will. If changes are required for your tune, you can always have them revise your custom tune, get it emailed to you, and upload it to your SCT device. The SCT website has info/download to add/change tunes to your handheld.
