what you're really looking for are 3 even bounces from each chamber. the actual compression number varies with the tester (+/- 20psi, round up all the testers in the shop, and test them on the same cylinder, they SUCK), cranking speed, how much fluid (gas lowers it, oil raises it) is in the engine, weather etc etc
