Would a custom tune really do anything extra at this point?
The canned tunes are tranny only, 87 tow, and 93 performance. What do most people run on as far as canned tunes go for everyday use?
Unless you put 91+ octane gas in your tank, I'd use the 87 tow.

But, even in your case, I think custom tunes will be even better. Not "blow your mind better", but, better. I know I gained about 0.5 mpg with the custom tunes and the driving experience feels even better than canned.
