The cars been running fine. The engine makes some noise but it may just be my ears not being used to these engines. I am use to gas. I checked the blow by and it was fairly strong which is why I bought the compression tester. This is a similar one I bought

I hope I am doing something wrong. Since I don't want to replace the engine.
Normal is in the 400 range?

I screwed the fitting into the injector hole and it fit snug.
I turned the engine over the way the directions say to. I put my foot all the way down on the gas and cranked the engine over 8 times.

Any idea on what I did wrong? Or can this be my correct reading?
