ok i am not sure if this is a problem or not. i was just out datalogging a new tune doing some wot runs to about 5400rpm in 3rd gear. i noticed that the oil pressure gauge was dropping pretty quickly around 4500 rpm but as soon as i let off the gauge would return to the middle (stock gauge). i am just wondering if i have a real problem or the gauge could be faulty. it doesent make any funny noises that i could hear. has anyone ever had this issue before.
