I seem to recall a chart somewhere on the forum that cross-referenced the integration level to the version number, does anyone know where that is? I searched but haven't located it yet. I just checked my integration level at my local dealer, and I have a pretty old version on my 5/2008 build E93, E89X-08-03-520. I do plan on getting a tune in the future, and I'm curious to know if just the version update alone will net gains similar to the OP. Any thoughts?
