so im looking at getting a tuner. i normally fill the car with 94 from chevron which is the besst i can buy in canada. it has 0% ethanol
in my searching i kept seeing conflicting information, a gti forum was saying octane ratings are the same between us and canada ( which makes the most sense...
I stumbled across this and read the entire post. It is a really good and interesting read on octane on your 'boost.
