Rolled 145k miles.
Decided to do a quick compression test yesterday when I got up. I ran the engine so it was warm.
Highest cylinder was 230 psi
Lowest cylinder was 200 psi
Quite a jump from last time I checked it at 125k back when it was stock compression. I put PRC 260 cylinder heads on since then which have the smaller 65cc chambers. Last time:
Highest cylinder was 193 psi
Lowest cylinder was 170 psi
Not too bad especially since it was supercharged for 70k miles of its life.
Mobil oil all its life every 5k miles.

How is that new combo working for you? Break into 10's yet?

Im still getting the tune dialed in. Im having KR issues that hopefully is injector related.

Miles and usage considered - that sounds awesome! Keep sending her all the way!
