has only heard of, have an opinion on, or used this as a octane booster?

I have not tried it but have head good things about it. Some of my GN friend swear by it. I think there is a video I seen sometime back on Horse power TV were they ran it on a Dyno and the motor they were testing made more power by advancing the timing. So it seem to have worked.

Just wondering what you are using for a tune? If you can advance the timing, like you can with the HP Tuner, then I think you would see more benefit. Not sure how much the stock ECU or the Arrow PCM will recognize the added octane.

From what I understand from mark j, arrow PCM will recognize and advance for up to 95 octane (I also called drive SRT and they confirmed with arrow that the stock PCM would do the same). I'm in Cali so we have 91 as premium. I'm going to mix 95 for my viper and I also have a 67 Camaro that has a timing box that can be set for 91 or 100 octane. We have a vp race station that sells 100 octane at the pump for $9/gallon and when I use 4 gallons of that and the rest 91 the car feels faster than straight 91.

It won't "recognize" the octane - it has no way of knowing what's in the tank. What it will do is not pull timing because the knock sensors won't be seeing knock.

The negative issue could be the resultant Stoich number. If you change it dramatically, your true a/f target will not be met, therefore, you could drop hp.

You just have to know the resultant Stoich number to predict the results.

I think Arrow has said that they see small gains to 95 octane and after that it begins to fall off. I know with that product you can mix it to get a desired octane rating. I would try to get your mixture to 95 octane and see if the car likes it.

That's exactly what I'm going to do. Mix to get to 95 for my viper and I'll try a 100 octane mix for my 67 Camaro. In the past I've been buying 55 gallon drums of 100 octane and if this works, mixing to 100 will save me approximately $250 on 55 gallons of mixed 100 octane.

You would have increase timing to see a gain, the pcm does not know the Octane rating, the max wot advance is fixed.

If the car is experiencing KR, then, a higher Octane might help.
