This is a cross post from the general section - but please could someone review my logs to tell me whether my engine is in good condition and healthy? It is a completely stock N54 with 95,000 miles on it, though the turbos were replaced at 60,000 miles. I only ever use 93 octane / 98 RON. 4 of 6 injectors have also been replaced and plugs were done about 10-15,000 miles ago. The engine never seems to use a drop of oil, and other than the usual ticking on cold idle, doesn't make any noises. I'm interested in fuel rail pressure, boost targets, fuel trims and timing generally. If it looks in good health, I'll grab the MHD Stage 1 93 tune.

Thanks everyone!

Didn't have much time but at first glance your log looks pretty good to me. You're hitting target boost, solid AFR'S and timing is pretty good. You do have a post shift timing drop though which you might want to get sorted out but overall everything looked pretty good to me

Thanks a lot for the review. What is the impact of/reason for post shift timing drops? Does it cause engine damage?

Like psmitty, Surprised at 3 cylinders w timing corrections post shift. Otherwise seems ok.

Nope not yet. I imagine the back of the valves are pretty ugly.
