Octane Question

residentalien · Post by **residentalien** » Thu Jul 03, 2008 4:22 pm

My tunes are either 91 CAI or 93 CAI - but I cant find that gas anywhere!
Available to me are 87 , 89 and 92.
I have ran 92OCT with the 91 CAI Tune..I assume that is ok but I was wondering why there is not a 92 CAI tune..

Someone suggested I run the 87OCT and put in one of those octane boosters, then run the 93 CAI tune.

Any thoughts / suggestions?

Theres no 92 tune because 92 isn't common. 91 and 93 are.

You definetly shouldn't run 87 on a booster. 92 on a booster maybe, but not 87. They aren't that effective.

If it was me I would run the 91 Octane Tune with 92 Octane gas. Most of the 91 Octane gas I get is not really 91. The high knock retard shows that. So maybe 92 Octane is closer to 91.
