Warm idle from driving under LOAD (doing a couple hard pulls and idling right after) seems to be about 28.

Does this line up with others’ experiences? I feel like I shouldn’t be worried since I just had the pump replaced under warranty, but at the same time I wish it would just stay pegged at 30 PSI idle regardless of the temperature.

Warm Idle from normal driving: Attachment 1125135

Warm Idle under LOAD: Attachment 1125136
I have to say that mine is the same +/- 1; 29 to 30. Original pump with 1207 miles. 0w/40.
