PSI not the ratio. Thanks.

rule of thumb is around 120 psi with no more than a 10 psi diff between cylinders on avg

Mine has always been around 120. I am in alberta, full throttle, both plugs out. Each gauge will likely be a bit different. But the 07 where low in that year then ski doo bumped it back up.
