I searched..........

So I did a compression test on my sr20det and it was 140 all the way across. I know 150 is the good range, so is 140 all the way across ok??? I did it at a little below normal operating tempature(Does this effect the readings if not at exact operating temp.???) and yes I had it at WOT. Does it just mean my piston rings are wearing? Thanks for any help.
