Compression test
95° ouside engine cold
1 - 140
3 - 140
5 - 145
2 - 140
4 - between 135 and 140(137.5? Lol)
6 - same as 4
Is this good?

Yeah it's not bad. Engine being cold it's hard to get an accurate reading but what you really want to look at is certain ones being off from the others. Yours are pretty close so I would say your compression is fine.
I guess once I get my.front turbo rebuilt and it all put back together.I'll do it again but warm..
I get around ~130 on cold engine, but i'm not sure if the car not being run for a week beforehand makes a big difference (piston rings probably dry). also have cams so that might make a tiny difference

I still get an average 140 with 219k on my engine.
I haven't run her in weeks.. and its stock internals. Looks like my oil was only front turbo bad heh...
My engine is about 150-160 with Wiseco pistons.
mine is 125-130 on all forged internals. came like that form laniers speed shop. he bored it a bit larger than .060 to handle taking a beating. he builds 7 sec drag cars btw ;)
mine was 150ish. but its more about the % difference between cylinders. your engine is fine
