Different compression ratios for the turbo and non-turbo engines. The year would be helpful, too.
One being down 10 psi isn't a big deal. I assume that this is a 'dry' test. A 'wet' test involves squirting in a teaspoon of oil or so into a cylinder, and testing it again. See how much the compression increases. If it doesn't increase much, that's a sign that the rings are OK. A big jump implies a ring problem.
Those numbers don't sound too bad for either engine.
