I have about 70 miles on the car just making a trip around my neighborhood every few weeks, and I'm getting about 4 mpg with occasional fouled plugs and a lot of popping on decal as the raw fuel detonates in the exhaust. I've heard a lot of good things about the Holly Sniper, so I fully expect to solve my hyper-rich condition with this swap.
