Ive seen that healthy f22s normally rate between 235 - 255. My car only has 45k miles on it. Am i worried for no reason? Could this something easy to address? Thanks for the help! Fwiw i dont actually own the car yet but the paperwork is complete and im picking it up thursday. Just wanted to see if this was something i should be concerned about?

Consistency is usually the key. The numbers could be low based on the method you used. Again, what you want is consistency across the board, thus those numbers look good.

I appreciate the reply just wanted to make sure it wasnt anything major..anything that can be done from a maintanence perspective to make sure these numbers are optimal ..(spark plugs, valve adjustment, gaskets, etc) ?

Was the test done cold?

A valve adjustment may help but they would have to be very tight to affect your compression numbers.

"Low" would be like when I bought my old S2000 with a CEL thought to be from a faulty ignition coil (random misfire code). After replacing coils, CEL remained. Did a compression check, one cylinder was like 150 psi, all others were well above 200 psi. Problem was a bent valve from the previous owner mis shifting and over revving the engine.

Your pressure looks great. Like the guy above, consistency is the key.
