Highest Octane For Stock ECU??

Here is the original blog post and video, just for reference: XXX Racing Fuel Gains 14whp on Stock 370Z : Injected Performance Blog

The video basically speaks for itself. Baseline dyno pull, adding five gallons of the XXX gas, then running it again. We don't carry the fuel, we don't sell it, and we have absolutely no bias towards or against them. The company was touring near the area and decided to stop by to advertise their product. Being curious like everyone else would likely be, we took them up on their offer and did a dyno test then and there.



The power gains are almost entirely from the oxygen content rather than the octane level. The XXX fuel used has almost twice the oxygen as other products on the market, like VP's Q16. Was it an interesting experiment? Of course! Is it a fuel that we would recommend for everyday use? Not really. It is being marketed as an alternative to race gas, and I wish them luck in getting the product out there.
