K20/24 low idle oil pressure EDIT: Possible MAP/TPS sensor?

this car only races, doesn’t get driven on the streets

K24a2 tsx block, k20a2 head, DC 3.2 cams w/Supertech head package

Oil: Valvoline VR1 20w50

Fuel: X85

It is a fresh build and on a cold start it’ll idle around 30-40 psi (have AEM Xseries gauge) but after running it, and getting it warmed up, the pressure drops to 15-20psi when idling at 1,000rpm. When I get back on the throttle it rises back up to normal 70-80psi (ish). Any guesses? Normal? Suggestions?
Thanks and Happy Thanksgiving everyone.

Check the sensors behind the head or filter in the front.. might wanna get the seal in the back of the head incase it tears.. but try cleaning that one first.. if not ur gonna need to took down cam bolts better or resurface the head on the top and oil pump resurfacingat machine shop..they can repair them .. if all fails on ur build.. but I would go there because u can check rod bearings when oil pump is dropped..
