FerociousP is on a distinguished road
Default OMP lines filling half way

This has been a problem since I added the turbo to the n/a block. I've been premixing since.

The lines fill from empty to about half full in about 2 minutes then stop (one goes a little further). I am getting no check engine lights, no limp mode.

______________________________________-
possible other problems i'm experiencing that might (and I stress might) affect omp function

- questionable tps (falls out of spec quickly, dead spot)
- low oil pressure once vehicle warms up and about 2-300 miles after oil change
___________________________________
Things I've tried to remedy problem:

- Change oil nozzles
- rebuild vacuum spider
- test lines for flow and leaks (I made new lines from a tut on 7club)
- changed omp
- changed back to n/a N351 ecu and let it idle for 10 minutes with no effect
- had the front cover off when changing to t2 oil pump (this is the same front cover from before turbo just drilled and tapped for oil return) and made sure there was no flow issues to omp

__________________________
Questions i'm not sure about or if anyone has had experience:

- Could a bad tps be giving a weird reading to the ecu and affecting omp function??
- What else am I missing?

Help!
