With that said, with your mods, you are pushing the safeguard limits of the N55. One bad knock event could hammer the piston so hard that it squashes the oil film between the rod bearing and crank.
I strongly suggest never going moderate to heavy throttle in a tall gear (3rd and above) at rpms below 4000rpms. This is called a high load situation which can introduce a huge surge of boost and potentially low speed preignition (LSPI). In stock form, then DME is quick enough to respond to keep this from happening. With Stsge 2 and beyond mods, the DME might not be able to keep up.
While good practice,, changing oil often really isn't going to do much for preventing spun bearings.

Understood. I should be fine as there's a good chance it won't see anything except for normal street driving and canyons.
Now, this is definitely interesting/concerning since I send data logs to my tuner in 3rd gear from 3k-6k RPMs. My revisions are done now but I will make sure to keep away from this in the future.
