I do not know the tolerances for a 944 but the main thing you are looking for is that there is not a big difference between any of the cylinders.

When I had a compression test done on mine, the mechanic said that anything below 140 wasn't looking too good. I think I had 135 and 132, the other two cylinders were about 144 each.

Have you had a leak test? That will give you more ideas
