I know you definitely don't want to tow on a performance tune. The performance tune advances the timing too much which will give you horrible knocking when towing a significant amount of weight.
Not true; I tow on a 87 performance tune, and simply run 89 octane while towing. I've even towed on 93 performance tune with no knocking.
