I would not try to run that nitrous kit with the lower octane gas. I tried that in my car and it ran like crap with 87 octane, and it had a little detonation. You might try to back your timing back a little and run the 93 again.

Someone correct me if I am wrong but doesn’t the lower octane gas burn faster? So with a lower compression ratio motor I have been told that the lower octane gas works better.

I am confused, someone please explain this to me.
