NewZed Posted January 3, 2015 Share Posted January 3, 2015 The number is in the FSM. But it can vary with the gauge used. The proper word would be pressure. And, if you search around you'll find that it's variation between cylinders that is most important. Not the number. Quote Link to comment Share on other sites More sharing options...
