335i Check engine light ON/OFF @ 6000+ RPM?

I recently installed the JB4 tune on my 335i.

My engine light came on when I was going at about 6000rpm+ and it automatically turned off within the next 5-8seconds? This happened twice and I'm not sure what's going on.

I also installed an oil catch can, and to prevent the tube getting squeezed to hard when I put the engine body shell back on top of the N54 engine, I did not tighten upper nuts (closer to the windshield). I did tighten the two nuts down below though. Could this be the problem?

I recently replaced my spark plugs about 2000km ago, so I doubt it could be a misfire? but when I was going at 6000rpm+ @ 130km/h, it did vibrate quite a bit.
