my service manual says minimum should be 135

some of them with 135 minimum go up to 199 psi. but i think you have nothin to worry about. especially since they are all the same. if you had more that 28 psi in the difference of any 2 cylinders then youd have issues technically. but if it were up to me i would say any mere that 10 psi difference is signs of issues. i'm just **** about that crap though
