Whenever you swap injectors, it is very important to make sure you're pulling correct vacuum as it's very easy to create a vacuum leak when swapping injectors.

I am an idiot. I didn't even think about it leaking at the injectors...That's probably the problem too. I finally released that it was running like how it was when I was tuning my BOV without a check valve. Lean and shaky. I boost leak tested my IC piping and blew a pipe off, reattached and retested and I couldn't find any leaks. Started it with no IC pipe to eliminate that issue and had the same problem. Noticed vacuum was too near atmospheric. It's probably a leak at my injectors...I am so dumb.

Face palm big time. Pulled all my coils individually and cranked. Everyone arced except cylinder one. Started it and ran it with the plug disconnected. Sounded just like it has been sounding. So now my question is can I replace that individual coil? Or do I have to get the coil it branches off of as well (Confusing, I know)? Would running on 3 cylinders run lean? I feel so bad abusing such a low mileage motor.
P.S. I just reserved a set of plug wires at NAPA. I will put them in tomorrow morning and hopefully this situation will be remedied. So now the question is... how did I fry my wire/coil?

It will be fixed, but then I will be sad because no megasquirt = no lots of boost :(. What's weird is when you originally advised me to check spark I pulled cylinder 1 and it didn't arc then, but I assumed it was good and didn't check any others. Could the settings have been so messed up it just fried immediately? It was running....decent before the megasquirt.

Was probably bad before.I've seen a coil getting fried by the MS (wrong ignition options) and both cylinders it was on (1 and 4) lost their spark, not just one.
Yes, a cylinder not getting spark would result in the wideband showing full lean.

When I pulled all the plugs they trip arced 1 and 4 didn't when I tested them individually #4 arced sov I'm hoping I can get away with just the wires and not a coil
Edit: Checked again this morning, definitely no spark on cylinder 4 either.

I just ordered a new stock coil on plug for simplicity. Do I need new wire too? NAPA had the wires but auto zone had the best price on the coil. I'm thinking if the coil on cylinder 4 is bad it wouldn't output to the wire on cylinder 1. I am a bit worried about going back to megasquirt now. I don't want to melt another coil.

I just remembered something I wanted you to be aware of...once you get your ms all connected up, and it's running...DO NOT NO MATTER WHAT ANYBODY SAYS...DO NOT ADJUST YOUR IDLE SCREW. Don't even touch it. I had high idle issues, and still do actually, but it's all because I never really took the time to mess with my closed loop idle settings. I look at it this way...if the stock ecu idles the car just fine, why should you need to make a mechanical adjustment when adding a different ecu? It's the new ecu that needs adjustment! I don't care if somebody puts a gun to your head and says "adjust your idle screw", tell them to fock off... DON'T TOUCH IT.

I won't touch it....however I think I just did a bad thing to my motor. I got my new coil, installed it and everything was dandy, so I was itching to take it for a drive. I let it get up to operating temp. and pulled over to check if everything under hood was good. The turbo was smoking, but I assumed this was just burning the oil off the outside. When I first put my feed in I didn't have a restrictor so oil spilled out, now I have a restrictor and there is no more oil issue..that I know off. So anyway second gear it transitions into boost. There is a loud pop and immediate loss of power. It runs rich when driving, but at 14:1 at idle, usually. So...did I blow a piston ring? Or something...lol looks like I'm building my motor (I say lol but I'm actually crying).

The smoking thing is, I assume, because I spilled oil onto my turbo. When it hit boost there was a loud "pop" sound. I lost power immediately, and afr's were rich (12:1). Now it just stalls when I start it.

That's what I was hoping. I couldn't see or feel anything disconnected but I didn't have a lot of time to check. I'm hoping I just missed it. Especially because I didn't see any smoke, nor does it smoke

I bet you popped an IC pipe coupling. On my SR20 turbo, it's really tight where the IC pipe meets the compressor outlet. I had it pop a coupling off there 1 time at Numidia drag way. It sucked to fix cause it was really tight to get to, and I could barely see there was any seperation at all.
All in all, I highly doubt you blew something internal...
