I would not think there is that much difference between an 87 and an 89 performance tune. I seriously doubt having those TWO custom tunes would be worth the cost ($30.00 for each I believe).

Since you DON'T tow anything, I'd replace the #1 Tranny tune to an 87 Octane custom tune and leave the other two alone. If you ever decide to fill your tank with 89 octane, you could just add 1 degree to the timing in that tune.

The only time I reset my tunes is when I switch from a towing situation to a prolonged non-towing situation. I think most of us work that way, we load the tune we like and just keep it there.
