N20 compression

[nickn20]

Hey guys, I recently did a compression test on my n20 and all cylinders ranged from 165 to 175 psi. What should the numbers look like in a good n20? My engine does also have over 200000 miles so I am wondering if these number are low or normal.

No idea about the N20 but those are good numbers for BMW I6's. More importantly, all your cylinders are within 10% of each other.
