With your compression tester you should have 3 possible fits just match up your spark plug to the size.
145-150 is great compression on a supercharged doo.
But my tester reads 130-135 per cylinder and my mechanics tester reads 145 per cylinder.
Every different tester will give different results.
As long as all the cylinders are about even psi your good to go.
