Reflash options for 94 octane?
I was under the assumption that the Vishnu reflashes could be done for higher octane but after talking to them on the phone yesterday, I was told that they only tune for 91 octane. I understand their policy to do this because most people that they do work for will only have access to 91 octane and Vishnu themselves are located in a state that only offers 91 octane.
What what about the handful of us that can run 94? If I were to get a Vishnu reflash, would 94 octane increase performance, make the car run "safer" or just be a waste of money?
As far as I've been able to pick up, it looks like scoobysport-usa and Prodrive (soon) are the only US companies offering reflashes. Is the market of 94 octane users too small to justify the cost of developing a map?
The Prodrive ecu reflash is tuned for 93 octane, but from what I've heard it's set up for either a stock car or one with "light mods". So far, what's luring me to Vishnu is that they seem to have tons of maps for differant configurations. (Yet, if you are close to one of their Stage setups, it looks like they ship you a base Stage X reflash becasue the ECU can learn around it).
So, I guess my question is, "Will me running 94 octane help or be a waste of money?" and if it's a waste of money "is it worth waiting for a company to offer a reflash based on a higher octane rating?"

I wouldn’t Run that Sunoco ULTRA 94. It contains Ethanol, Im pretty much at a TXS stage IV with some other mods and I use Mobil. I heard ethanol eats up your seals and all kinds of other stuff.. (I may be wrong though)
Mobil
Amoco
Shell
Citgo <--- I think
BP
Are all ethanol Free, If you read the pump where you are filling they tell you what they add (10% ethanol). Ethanol works like a octane booster. Its cheaper for the Fuel Companies to make their product, and that means less refining. I did alot of reading up on this and found the same amount of positives as negatives.
So after saying all that, I steer clear from the Ethanol (Just say no!) =D
and I think from 93-94 isnt a big jump anyways.

It's not worth waiting for. Perhaps you can run a few more degree's of advance with higher octane. But personally would want to tune for a lesser quality of gas that way if you ever do get a bad tank your car wont pull back as much timing.
Even if you are tuned for 91 octane, and you run strictly 94; look at it this way... You'll always be running the maximum advance for your particular reflash.
And as far as Prodrive being tuned for 93 already... They have not yet released their US maps. So that 93 octane figure may as well be a euro spec remap.
