I wouldn't think the pressure would be affected by vehicle movement/position if it were a bearing. You may want drop the pan and confirm there is no debris in there getting sucked onto the pickup screen. I would also look into the sender/gauge circuit. If the sender is still in the stock location, it is very easy to crack them as the intake is being installed. If it has been relocated with any sort of adapter, be sure it is grounding to the block. When I relocated mine with the Kenne Bell kit, the adapter and ptfe washer did not provide good continuity from the sensor to the block giving me very erratic pressure reading.

Did you check it with a manual gauge? and can you post pics of the filter? Here was my filter when both my main and rod bearing went to ****:

No I've been painting my wife's car and DDing the hoe. Being that it's broke I have to make a mad dash to get her car put back together so I can drive it. I'll get to the hoe this weekend. This thing is a pain in my ***. But it's so freaking fun to drive. I feel like a kid at Christmas every morning that I drive it. It's been that way for like 6 years now yet it never gets old.

My filter looks close to the one in the pic. Wtf causes this? Running too low of rpm locked? My settings for the Tcc are stock which can go down to 1000 rpm locked up. It just tugs along.

Exactly, up hill is worse than down hill. Turning such as a 90° turn from road to road makes it way worse.

What are the cam bearings made of? My oil pan looks like a episode of gold diggers.

Ok mains are shot. No silver left in them at all. Rods look good though.

Check the cam bearings too now that you've driven it with low oil pressure

The edges seem to be more worn.
