Are you guys running that much compression or timing that you have a need for it?
^^^im at 11.8:1 static and about 10.6:1 dynamic compression ratio. im also running it with the timing advanced some. love the setup but it’ll deisel a little when i shut it off running straight 93. the octane booster/higher octane seems to take care of that. besides i dont feel like having to replace head gaskets and burnt up valves from too low of octane.
