87 performance custom vs. 93 canned
I've been running the 93 canned tune mostly since getting my Gryphon but fuel prices are beginning to creep back up and I'll probably go back to 87 octane before long. My question is, how does the 87 performance custom tune compare to the 93 performance canned tune? A few more questions on custom tunes...
Will a custom tune need to replace one of my current canned tunes?
Will a custom tune include include things like increased shift firmness, TC lock/unlock? Or will I need to go in and change these manually?
