HI
I have an 07 gmc sierra 1500 with a 6.0 and Idle oil pressure drops to about 15 when in its gear at hot idle and about about 20-22 psi when just in park hot idle, some days the hot idle in gear is 20-25 sometimes lower, I had the oil pan dropped a couple months back for an oil pan gasket and cooler lines and they check O ring and they siad it was in good condition and changed oil recently too, the cold start pressure is about 50 and when driving around 2,000 rpm 35 psi hot driving and when at 3,000 it’s almost 40 at hot driving what can I do to improve hot idle oil pressure was thinking about changing oil pressure sensor since it seems to be different pressure at different times at idle which doesn’t make sense at same hot idle, would using a range tune and delete afm help the idle hot oil pressure when it’s in gear because as soon an it goes into park oil pressure goes right up to 20-25 psi so doesn’t make sense
thanks in advanced
Jacob
