When you test it you may get 250psi and you will think you have low compression, when the adapter is actually too small and you can't build up the compression enough because it doesn't fill the injector hole. We made some at work, and if they aren't right they aren't accurate. You can compare between cylinders to see if 1 is lower than the others, but the reading is low across the board.

No biggie.
Why do you need one, as in do you want to check it because of the miss you were talking about?
