Re: 89 and GT Performance
I'm not an expert, but I think if you run another tank of 89 in warmer weather or up steep hills, you may notice a difference. You had some 93 in the tank, so your mix was over 89. There's a knock sensor, so you should not hear pinging, it backs off on spark timing so you lose some power. I'll bet you could alternate filling up with 93 & 89.
