Low compression across the board.

Low compression across the board.
Ok I'm now scared I just read the melted piston thread.......
Anyways. I have low compression across the board.
94 1.8
#1-105
#2-110
#3-105
#4-105
Car has 114K miles on it
Checked my timing as to the E/I and the I on intake straight up and E straight up as well as having the crank lined up properly with the 1 and 5/8's turn. Car for the longest time was run stock ECU with Apexi SAFC but the SAFC failed at some point IDK when. Was later bought by me I have installed a MS1. It is not tuned properly right now I will say that but it's tuned rich. And I do NOT get on it when I do drive the car. This car also burns oil like crazy 1 quart every tank roughly maybe a little less. I do know that it leaks some oil as well IDK if it's from the crank or cam seal or the oil pan but if I need a new engine I don't feel that I should be digging into this engine to replace seals which aren't causing too much issue right now.
Turbo is a TDO5 Small 16G will build boost very slowly if I step on it at 2500 rpms it will go to 1/2psi 3K-3.5K 3-4psi and 4K rpms it will finally hit 5psi which is my max for now until this car is tuned and running properly.
Also before I put the MS in it the car would blow blueish/black smoke on startup after sitting for 6+hrs for .5miles like mosqito (spelling) cloud big crazyness now after the MS1/speed density/IAT/ and IAC unplugged No smoke WTF?
Looking for input onto what tests I should do what you guys think... ECT ECT ECT.

Just a little background bought the car 3 months ago spent 2 months just getting it running, I've replaced more than half the drivetrain bc of stupid previous owners so you being a jerk and calling me the problem doesn't help me. I get on forums bc I like to get to know the people in my comunity thing is when I find people like you that just love to be a jerk it's a big turn off. So maybe I don't know how to tune how many people do? atleast I'm not some dumb 17 year old who bought a turbo miata and starts sayin yo how I make dis shee fasta. I try to do things right ask for oppinions before I jump the gun. Anyways rant over....
No I have not cars been sitting for 3-4 weeks now on the plans to get another engine. So SVO? You own one? lol

Burning oil will ruin your wideband sensor and also make it read incorrectly so you cannot tune it as is. Burning oil causes premature detonation because oil has a lower octane value, therefore you cannot boost this motor. Hence, you should rebuild or replace engine. A leakdown test may help you determine the nature of the problem, which would be useful if planning a partial rebuild, but I would go junkyard or fully forged rebuild.
