Scan for codes in case one is latent but not showing CEL.
Look for a cam sensor or phaser related error?

Not saying this is your issue:
There is an oil restriction orifice in the heads.
It is different in GT/GT350 heads
Are you running GT350 oil pump? or GT? or track variant pump?
You are running GT350 phasers or upgraded GT phasers?
Which exact part number?
Somewhere on FRPP I think I have seen a note about the combos of which oil pump and which restriction orifice to use in conjunction with which oil pump and/or phasers. Cant recall which dependency takes priority in determining which orifice/restriction to install.

Oh yea, the restriction might be on the firewall side of head, oh joy...

Could be other things...
