so I did a pull the other day and my car started to smoke and sounding like a subaru. I got home did a compression test and I got the following numbers 180/0/180/170. I have not done a leak down test since I don’t have a compressor at home, I did take the intake manifold off and the valves are pretty cake up with carbon build up.
I also put a camera down the #2 cyclinder and it looks fine, of course I can see the rings so irk if does are fried. So I was wondering if anybody seen this before or think it might be the build up on the valves. The car is a 2010 with 85k no egr delete or catch can on it. Mods are: hpfp, solid mounts 2.5 intake and 3 inch turbo back. The car is also tune an it’s making around 300hp/350tq
 
I hope you're running some kind of alcohol somewhere, either e30+ in tank or methanol from WMI. If not, this log is a bigass yikes.

Not a true/good comparison, but here's my car running E35 with lots of room for timing left:

Whoever tuned your car is looking for knock feedback and didn't get any (which is as to be expected). You've got busted ringlands for sure, and to have zero comp, I'd wager there's a nice fat chunk in your oil pan currently.

Edit: Assuming there isn't just an outright hole in the piston.
 
I see. well ill be dropping the pan this weekend ill port an updated. thanks for the quick responds brother

Not too sure you're going to be able to just do an engine swap man.

I’ve been in contact with a couple of guys that have done it. It sounds pretty straight forward but as you know with everything that sounds too good to be true. I was told all I need pretty much is add a return and feed for my turbo

Hey can you tell me what did you use to look at the log?

Go ahead and post another one if you have it. Honestly won't help much though. The tune is clearly not even in the ballpark of being reasonable. Find a different tuner once you replace/rebuild your engine.

i will for sure. if is in the block i already have the funds for a semi build block, since i already knew it was going to happened sooner than later.
