I think you'll be fine on 91. Just don't race the hell out of it. We only have 91 piss water here too. Tune it for 91 once you're here full time.

I'd bet 92 octane is often 91 or less. I don't quite know what the tollerance is on fuel grades but there has to be some.

Hell, they ship all the various grades in a single pipeline. They will flow 91 down the pipe and then 87 right after it. They switch the valves based on a complex system of timing the flow rate to know where one grade ends and another begins.

I guess you could always bring a few gallons of toluene with you; half a gallon for ever 10 of 91.

That is exactly what I am doing at the moment. I switched to my pump gas 94 octane and run a big mixture so the car does not knock.

Sounds to me that Mark Jones Tuning guy is the man I want to talk to about a fresh tune.

The Torco actually works well for raising the octane but I would not recommend it for long term use as it tends to leave alot of deposits in your motor over time.

Toluene is 114 octane so you can do the math to get the octane rating you need. Do not use over a 20% mixture of it though. It is great for being sneaky at certain races as it does not have the telltale aeromatics they put in race gas to keep people from cheating..

Torco does work. When I first got my swap it was tuned for 93 and would ping in warmer weather. I would throw a half can of Torco in per tank and it would run like a champ.

It does leave deposits so I wouldn't want to run it forever.

I think I have a couple cans in the garage still if you need them.
