91 octane?

[packing8]

i live in las vegas and they only have 91 octane can i still use a 93 chip? thanks. there is a 76 down the street that sells 100 octane but i cant afford that stuff 4 bucks a gallon. Maybe i can mix it with 91 to bring up the octane? maybe 4 gallons with every fill up?

Chip with 17-18 degrees timing WOT, 15-16 psi boost, and around ~800mv fueling should work OK.

You may want to consider alchy injection. Works for me using 91 octane.

Variable timing chips are perfect for your situation.

Yep, I've gotta agree with that one! I used one of Jay's variable chips with 91 octane and it worked great!
