Oil pressure drop at cruising speed?
After recently installing and tuning my 780cc injectors to idle I've expereinced lower oil pressure at cruising speed. Approx 10psi lower at 70mph in 5th gear. Oil pressure at idle is still good.
I have some hunch that while trying to get the 780's to idle properly the extremely rough idle (at times) could have damaged the oil pump? It would seem this would cause pressure to be low at idle as well, but it's the only thing I can come up with.
Any ideas?

so whats you pressure at idle and 3k rpms?
i mean i dont see how changing the injectors would have anything to do with your low pressure.

Pressure at idle is around 25psi. It's around 60-65psi at 3k rpm.
I didn't mean the injectors caused the lower pressure, but when trying to get them to idle the engine did a lot of rough clunking around. The vibrations were very bad and I just had a hunch if anything has recently caused any damage that would have to be it. I'm not saying it did anything at all, but its the only thing I could think of.
