As I type this post, we are working on right now, I have the code and we are disassembling the code now to figure out the encryption to flash through OBD II. We found most maps already to tune the ECU.

You should use whatever grade/octane the owner's manual recommends.
I recommend reading the US Federal Trade Commission's Facts for Consumers - "The Low-Down on High Octane Gasoline"
http://www.ftc.gov/bcp/edu/pubs/cons...tos/aut12.shtm
If your vehicle is experiencing engine knock (or pinging), then you should go up a grade in octane. (But if your vehicle is fairly new and has engine knock, something else may be wrong and you should seek a tune-up!)
Octane is a measure of the fuel's ability to resist pre-detonation (or engine knock). It burns just a little bit slower.
Higher octane gasoline doesn't mean that it is necessarily cleaner or better. "Premium" or "super" is a mis-nomer. All gasoline sold in the US must meet certain federal EPA clean-burning guidelines. However, some individual brands _may_ decide to put some extra cleaners or do extra refining in their higher-octane fuel (as I've heard of some brands advertising low-sulfur gasoline as only in their Premium line).
A higher octane gasoline actually has lower BTUs (energy content) than a lower octane gasoline, so the only way that you'd see better fuel economy by going up in octane is if you were previously using lower than recommended octane in your car... (So expect lower fuel economy in most vehicles by using higher than "regular" octane gasoline.)
For an occasional tank, you could get away with using a lower octane than recommended in a vehicle that requires "premium" fuel, as the car will adjust, but it can cause some extra wear on the engine while knocking, besides the lowered fuel economy. (long term use can cause additional engine wear/damage)
If you live in a high altitude area (like the Rocky Mountains) usually you can use the next octane level down from what is listed in the owner's manual because of the altitude/thin air with no ill effects (except if you come down from the altitude with a full tank!).
For some cars, such as the Toyota Prius, using higher than the recommended octane fuel is known to cause check engine lights with engine misfire codes (because of the Atkinson cycle engine, rather than the Otto cycle engine most other cars use) due to the late detonation, besides the expected lower fuel economy.
Reasons to use higher octane fuel:
1. Your owners manual calls for it
2. Your engine is knocking
3. It's the only way to get low-sulfur fuel in your area (sulfur will slowly poison your catalyst, making emissions worse over time)
4. You like spending extra money on gasoline
