Enthusiasts are excited but cautious about a new calibration for 2015-16 Corvette Z06s.
Chevy recently announced a 100 Octane Fuel Calibration that aims to help Z06 owners who use their cars in performance environments (whether automatic or manual transmission).
Apparently, the change can be accomplished at any Chevrolet dealer at a cost of $332.50 and doesn’t have any effect on the warranty.
Chevy says the upgrade helps lower inlet air temperatures during “spirited” driving, but some on Corvette Forum are skeptical about it being any kind of fix for the overheating issues that have plagued some hard-driven Z06s.
The change also doesn’t affect emissions, but the kit includes a new emissions label, calling for 93 octane to be the minimum octane for street driving.
We’re waiting for someone on the Forum to tell us how much of a performance upgrade there is, though you might want to check on your bank account before committing to the change since 100 octane apparently costs $9 a gallon at the track, according to one post. As he put it: “I use 10 gallons in 20 minutes or about 50 gallons a track day, not including transportation. Pumping 100 octane puts me at $450 a track day, and well over 15 grand in gasoline costs a year. Doing that math I can’t afford it. But I’m sure someone that lives out where 93 octane is on the street and drag races, which is most of the Corvette owner circle from what I can tell, will dig this. Enjoy!”
Another driver was happy about the availability of the upgrade since “it also lets us know that GM is watching, and acknowledging what we do with these cars.”
