My oil pressure keeps going up when I accelerate. The oil level is good it is exactly on the line.

Oil pressure is supposed to go up slighty when accelerating.

Is oil pressure going into High / Red zone?

Ok ince it is going high but oil level is not over or under you will need to test the oil pressure with a mechanical gauge to ensure the in-car gauge is accurate. If it is accurate then the oil may be too thin (wrong vescosity) or worn out, or the oil pump may need replaced.
