Could someone look over these logs and let me know if there is anything to worry about, i can get more logs with different info if needed. I picked up a compression tester to trouble shoot. just a little worried cause i have been seeing a few low neg corrections on random cylinders while normal driving, nothing over -1.8 most times its under -1. looking to go BT soon and want it all to be good so it doesn't got pop sooner than later. the fist log "stage 2" is old, but the only thing different is new plugs on the other two.

Looks fine. OAR is -1 and I see very few neg corrections in there. Compression test is still a good idea I think before diving into the BT, and at least will give you a good value to compare to later down the road, should other issues arise.

Hey man, a little suggestion; it might be better to put the actual subject in the header when posting stuff like this. You would attract more attention with "A little help with my log files please."
And no, I don't know nuttin about log files!

Compression test went well.
cylinder #1--148psi
cylinder #2--143psi
cylinder #3--148psi
cylinder #4--148psi

looks like healthy skepticism about the car being off, i think the car will feel better once it gets a custom tune. OTS are safe for now.

I have just under 70K and it is a early 2014, date built was Oct 2013, so its one of those weird in-between ones.

Gotcha, I'm at 62k with mid '14 build and my compression was just a tad above yours. I too, am eyeing up a bigger turbo. Good luck sir.

I wouldn't read too far into the actual compression numbers-- these gauges seem to vary widely and of course your elevation/temp/how hot the engine is/battery condition are all going to play into this. Hell, the gauge I have sits at +20psi, so I know it's reading way high, but it's consistent and that's what matters. I believe most service manuals want something like no greater than 10% variance between cylinders. Yours is a little above 3%, no biggie. Usually my technique for this is to run a compression test, if one or more cylinders is abnormally low, then I know something is up and further investigation is required. At that point, I'd get a leakdown test to further gather data and narrow down the issue.

what turbo are you looking at going? I am looking at JDLs Kit with a GTX2871 EWG.

GTX2971r for sure. Then after I get bored of that, idk. I also have a ton of supporting mods for big turbo. I probably have one of the most modded ST's kicking around, and most likely the most heavily modded Untinted ST, and for sure the most modded Lease vehicle on here, lmfao. (At the time going with a lease was the best option I had, my credit was ****, yes I'm buying it out, lol."

If turbo IMO BorgWarner FTW
EFR is the way to go, but I built my car currently for a GTX swap. So until I do a motor build and start going crazy, the GTX is for me.

How long of a lease? Usually leases are like what, 3 year 36k miles? And then like a $.25 a mile overage fee... You're at like a 7,500 dollar overage fee. You should act like you're going to turn it in, leave all the mods and stuff in there too. Man, I'd love to see their reaction when they start it and see the high ass miles and how much the car vibrates.
