Ummm... I was unaware this is even a possibility.I am probably going to get a YotaWerx tune package for my GX, with an 87 octane tune for normal use and a 91 octane tune for pulling our camper (when more power would be always nice).
FYI, I usually run Top Tier gas in almost all of our vehicles unless I'm in a pinch where I need fuel and only off-brand stations are around. Then I add a bottle of Techron at every oil change to keep things clean. My previous 13:1 compression Mazda 3 did definitely not like cheaper fuel - although I have not noticed any difference on our lower-compression vehicles.
