Is there any safe product that I could add to ethanol free 91 octane gas to safely run the 93 octane tune on my Predator???

And if I do, has anyone datalogged with a Predator to check timing and knock??? Thanks guys!!!

Got the first drag day of the year on Sunday and I want a new best slip!

Looking at Torco Accelerator or Lucas Oil product...any experience with any ??

I have heard/read good things about the Lucus octane booster and the NOS octane booster. Ive used both, but have no data to back anything up. I found a chart online that showed how much the octane increased with each product (lucus vs NOS vs toulene etc) and ill see if I can find it again. The chart showed that the octane gaines were not linear, meaning that the first bottle might increase the octane 9 points (from 91.0 to 91.9) but the second bottle only increased it 3 points (to 92.2).
Personally though I don't trust trying to calculate the octane after adding octane boosters. There is so much missinformation out there and I only know of two proven products.
1) mix unleaded race fuel with your 91 octane
2) mix toulene (tons of info online)

This is one of the better writeups about octane boosters I've seen. Here's a link.
