wondering if you guys have ran any gas treatments in your coyotes yet? I tried one time maybe day two of having the car and not knowing about the funnel in the trunk I just tried to pour it in the tank and it just all ran out behind the wheel. I have the steeda 93 tune on my car and just got done reading some posts about the #8 cylinder issue. I do know that supposedly steedas tune is the safest out there with no issues yet. Anyway I was thinks of adding a octane booster just to be safe.
Steeda's tune is safe and I have never seen an failure due to an #8 failure with their tune as you mentioned. Also if you are going to run something, use the white funnel that should be in the trunk. I believe mine was attached to the spare tire on the lugnut wrench. Most of the those octane boosters do not raise the octane like it states on the package but some fuel system cleaners are legit.
