At elevation 91 is much better than 91 at sea lvl.

93 since I've owned it.
Yes, but is 91 at elevation equivalent to 93 for a 93 tune re knock prevention? Would I dare go to a 7% OD damper with stock tune on only 91 even at elevation?

I have had more than 1 Super charged motor and not sure what your asking?
I had a 93 tune on a Vortex SC formula and had to run 91 from Kansas to Wa state and had no issues.
Is your tune for 93 at 4kfeet than no.
If your tune is at sea level I would have no issue running 91 to cross an area. If I lived at altitude I would ask the tuner... or have it tuned at altitude.

Pretty much Shell 93 for mine
There’s an amazing thread on this on the other forums over at the other Hellcat forums.
It was actually eye opening. Guy with a lot of technical knowledge - and equipment to match - posted all sorts of charts and tables chronicling his drag runs on different fuel. Amazingly, he experienced 4-5 degrees of knock indication on 93 gas (probably with bad DAs, but still surprising). He experienced this consistently until he mixed in race fuel that got him to around 98 octane.
Eventually, the thread expanded on others’ experiences with octane boosters, which a lot of guys use to save money and headache. The boosters all left orange, caky residue over basically everything it touched inside the engine, including valves, bore walls, etc. Someone took the time to do a tear down and post pictures. The residue could not be cleaned off with a rag and needed to essentially be polished or buffed off. It was pretty eye-opening stuff.
If you’re not running a tune, you probably shouldn’t worry about it at all under normal conditions. But everyone who had the data agreed that 98 was a good number to achieve for a day at the track. For $100 or so, I think peace of mind and a clean engine make it worthwhile.
MMX sells a 7% OD lower dampener that claims it runs fine on the stock tune, so no PCM unlocking required. If it's already pulling timing on the stock 93 tune because it's so aggressive, the 7% OD would likely require it to pull even more timing. Add in only 91 and it gets exacerbated even more--unless the altitude really does compensate for it, then it's back to the original problem of how much timing still gets pulled with the stock tune and 7% OD added...

Oh.. let me change my answer... I would not drive on 93 with a pulley unless it was tuned.
They claim the same thing for the 3.17 upper pulley--that it's mild enough it can run safely with the stock tune. Only adds about 2lbs of boost, about 25-30HP bump.
Shell has the biggest additive package in their gas, but 93 or 91 from any of the stations on this list are good:

I am a New Yorker ( or born in the state) they claim all kinds of crap. I would not drive a car with a Mod with out a tune. I think my stock Super Stock pulls timing on 93.
