The first year I ran ITC I had the same concerns on my engine. I asked around, and several knowledgable VW guy's gave me this advice.
Run it till it blows!!
If it's running good, don't worry about compression or leakdown numbers, just drive it. Especially if your new,(Welcome!) concentrate on improving as a driver, don't worry about the engine for a few years. When you can keep up with everybody through the corners but they pull away twords the end of the straight, then you need more power and it's time to work the engine!
