Any number of information sources accessed through an internet search using prompts such as 'gasoline' and 'octane', repeat the same information: that higher octane gasoline simply burns at a slower rate and is less prone to knock than lower octane rated gasoline. It isn't 'better' or more powerful gas. Admittedly the high octane gas contains more proprietary additives than they put in their regular grade of gas, the nature and amount depending on the petroleum company marketing it. (The gas companies put these additives into the gasoline after it has been refined and once it has been earmarked for sale in their particular branded outlets. The additives certainly don't add any power producing capability to the gas.)

Whether spark and fuel tables are optimized for 87 or optimized for 94, the motors output should be pretty much equal. Optimized is optimized and the hardware (cam timing, valve sizes, exhaust and intake port sizes...) is unchanged.

So I still have to ask: How does the SuperChip extract more power from the same engine that is now optimized for and running high octane gas? What's the operating theory? Are there independant dyno tests?
Thanks.

Those kind of look like they were drawn with a compass.

Has anyone besides Superchips company itself, dyno tested their truck using the Superchips mapping for 87 and running that gas and then again with Superchips mapping for 94 or the equivalent, and using that grade of gas?

Those graphs appear to be comparing stock configuration presumably using regular grade gas and Superchips configuration, gas grade not specified.

You will definitely see better throttle response TQ and MPG using the different tunes included in the product.

Any further questions feel free to let me know.

Go with 3865, if you're aren't interested in the extended power train the Cortex offers.
