Non-ethanol vs 93

I don't know what kind of distributor you are using, but I had a couple bad experiences with Mopar Performance distributors with too much advance (mechanical plus vacuum). This time I sent my intended distributor to HalifaxHops and he recurved it properly to 36 or so degrees max. If not corrected, this can result in pinging due to too much advance (one we checked was up to 58 degrees!).
