Ok. thanks for the info guys. and yeah I dont mind running straight race fuel all the time as its not crazy expensive. (at 100 Octane)
But Eurocharged did get back to me this morning and he stated that:
"With 100-102 octane fuel, I would simply add it to the existing tune and benefit from the 10-15HP increase. I can only make a new tune for fuels that are 109 or higher."
I am guessing that this is due to reliability? at 109 Octane you can safely max out how much timing you want for this engine before you start to get diminishing returns. Too much timing you will lose power.. But, not sure otherwise.
Anyway.. 110 Octane UNLEADED race fuel runs about 13-17/Gallon Maybe I'd like to try that ONE TIME and take it to get the car dyno'd just to see the results. Otherwise that's way out of the question.

^^Also Only 91 Octane fuel here... LOVE CALIFORNIA!!!
