I have been a bit out of touch with this (and similar) threads. What are the odds that I can TUNE my '04 Ion 2.2 now with the latest version? Or would I have to mail in the file manually and download a "patch" to tune it? I will try to read it now. If I can read, save and see it, I should be able to tune it right? Don't want to waste the credit, but it's my daily driver and I would love to tune it for practice!
