ok, well , i got my hands on my friends compression tester, and me and 2 of my other friends with n/t's decided to check all of ours, mine came out 135, 135, 135, 130, and my other 2 friends were like 125, 120, 125, 125 .. now i know there is no way that is our compression, im guessing it was just a screwy tester, how much are new ones ?
