87 for me my car runs perfect on it. I have a friend of mine that just got a Z06 and he uses the 91 octane and it costs $3.45 a GALLON. I guess if you can afford a Z06 you can afford $3.45 a gallon.

You need nothing but a timing light. Its VERY simple.

I read that article and advanced a couple degrees but im not sure if it was at 10 degrees or not. How can i tell what my timing is at or at least get it back to stock?

I was/am running 93 but I found out the donkey who had my car before me set the timing at 20*!!! It pinged right as it shifted with 93* so I bought a timing light and set that biaatch back to 16* and it runs beautiful!! Mines not DD so I only run about a tank every two weeks to I ante up for the good stuff..............
