Compression? What Does This Mean?

[SlowWhite]

Ok a few months ago (probably 6 or 7 by now) Josh, Mike, John, Ryan I believe all have seen that my car's compression was around 155 on all 4(after 5 turns of the motor)

Now I can't remember if I had the 99 head swap done then or not.

We ran into some issues on the dyno and apon doing a compression test:

Tried 2 different compression Testers: (8-15 turns of the motor)
1st one)
-192 across all 4

2nd one)
-189-192 across all 4


Stock Max compression on a 2G is supposed to be what around 172ish?

Does this mean that my motor might be seizing up? (hopefully not crankwalking!)

Both on the dyno and on the Street I am not able to tune for a good power A/F. Due to the Car Knocking apon trying to lean it out?

I'm hoping to hit the dyno next week with Race Gas. To see if the knock sensor is bad. (I'll also be bringing my spare knock Sensor just in case)

Is the high compression part of the knock issues?

I ran the car almost completly out of gas and then filled up with 93 oct yesterday and did some more logs. With little improvement.

Basically if I Lean out the car anymore then 10.5:1 A/R the car knocks to where I have to back off the gas.
