The numbers will vary based off the individual compression tester, cams, compression of the motor, etc. You want to make sure the engine is fully up to temp, WOT, and disable both fuel and ignition to avoid damaging the coil. The individual value of numbers really doesn'tmatter, the important area to focus on is the variance between the numbers.
