loss of oil pressure..billet oil pump gear upgrade?

[RS4]

I have a 2014 Roush SC and awhile ago, the warning light came on "oil pressure low" and the engine cut off (thankfully). I restarted and didn't have it occur again, but it is concerning. Do I need that gear upgrade and will that prevent any future problems?

Also, it is a tough cold start, almost needs more O2 to get going???

And, when I shift gears from R to D and vice versa; the RPM real drops down to an almost stall?

Thanks for the input.

Is it still on the factory Roush tune

I assume yes...it was a roush dealer installed upgrade

I don't think the oil pump gears are the problem.

I'm positive you were about to stall out and did stall out like you mentioned, coming to a stop or slowing down and turning.
And like you mentioned shifting from D to R
I would get that concern written down at your dealer. And have them contact Roush.
Either you have a vacuum leak or the Tune needs adjustment.
Try a different gas station and only the highest octane you can find.

Stalling out in a Raptor while trying to make a turn is no joke!!!

yes when you stall and the engine cut off
your oil pressure readings at that time will trigger oil pressure low
because your truck think that your engine is still running but its not ..
check for vacuum leak or adjust the tune as MTF said

My truck was doing this same thing with the Roush tune but never stalled out. It would dip just below 500RPM when I would get on the gas and let off quickly at very low to no speed. Just had it custom tuned, runs better and did the same but worse. Almost stalled, then stalled out with the Low Oil pressure light coming on. I took it back and the adjustment took less than 5 minutes. The idle was bumped up 100RPMs and he did something else that added 5%. I don't recall what that was but the truck is back to normal and running great.
