As a general rule of thumb compression pressure reading should be no lower than 100 psi and should not very more than 25 psi between your highest reading cylinder and your lowest reading cylinder. It’s more important that all cylinders read about the same plus or minus 25 psi rather than how high the readings are, given that none read below 100 psi. However, you will need to do both a dry and a wet test to help determine which components may be at fault if any. You can also do a cylinder leak down test or a variant of a compression test can be done at a shop using a diagnostic scope that's capable of reading the battery amperage required to crank the engine over per cylinder.
