Having them all reading the same across the board is better than having one low cylinder..

Sounds like you did a "cold" compression check....If so you should be fine.

As Rosco said, warm it up then do it.

Your numbers are better than mine, I had 170-180 across the board then 115 in cylinder 4. A new KA was sourced after that.

yup... looks like a cold test...with tb closed....probably bump up some if you squirt some dw-40 and do a wet test on a couple of cranks....i dont think you should worry...

at least its 120 across the board, and its even..

The 120 just means you can run more boost now....
