When I try to run around that lean on mine it bucks and shutters. Is high timing the fix for this?

Keep in mind I was running approximately an E45 fuel, so the comparison isn't exactly the same. My 4.8 also has relatively low compression at 9:1, so it can take running a little leaner.

Probably too tight of a spark plug gap then.
