Car won't run

[S13x88]

Alright, so I just finished my ka-t project. Had everything plugged in, and it started, but barely. We advanced the timing a tooth and it idled perfect. Tried to drive it, and it wouldn't go past 2500k RPM, like a bad MAF. I plugged in another MAF I know was working, and same result. Rechecked my MAF wiring, and I had wired it wrong. I had the 12v and the ECU wires mixed up. Wired it correctly, plugged in the maf and the car would not stay on; it was gasping for air. Unplugged and it would work. So we set timing again to TDC and it still won't fire up. I just checked my ECU and I don't see any evidence that it fried (can't smell any burnt silicone, don't see anything burnt.)

What I've got:
Enthalpy tuned for N60 Maf, 370cc injectors, T2, and 93 oct
Freshly rebuilt stock KA
T25
370cc injectors
N60 maf

I had fixed whatever vacuum leaks I had before I figured out the maf wasn't even working, so at this point I'm at a loss. Is there anything I can check to see why it won't run?

Check IACV or boost leak

IACV is new. All of my sensors are new and emissions are deleted. When the car was running with the disco'd maf, I had found vacuum leaks that were taken care of. The car would run and idle steadily with the maf disco'd and one tooth advanced. As soon as I fixed the MAF wiring, the car will not stay on. What I'm thinking of doing is cleaning my plugs (they reek of gas) and checking for voltage continuity in the maf wiring. Other than that, I'm at a loss. Is there a way to tell if my ECU is fried?

Can you get a video by chance?

Maybe shorting grounds, but check boost couplers first

Is the CAS rotated any one direction fully? Also do you have a stock maf to hook up to see if they forgot to tune for n60

I bought this ECU from another member on here. To my knowledge, the ECU works. How would I move the CAS? Where is it on the distributor?

Checked my MAF wiring again. With the key on ON, I have 12V on the 12V line, both grounds were OHM'd for continuity; I got 0.3 and 0.4 on both grounds. I don't know how to check the signal wire with the motor off, since I can't get the motor to stay on. I checked the ECU for any codes and it gave me a 55. I can only think of the ECU at this point. Something is making me run PIG rich. I already have fuel in my oil. After cleaning the spark plugs, the car will start up after setting timing to TDC, but dies very soon afterward. The engine is just being flooded with fuel. I have a stock FPR, 370cc injectors (even checked the # on the injector to make sure they are 370) and a Walbro 255. All of my sensors are new. None of my injectors are leaking. I have the stock SR intake tube with a coupler attached and then the MAF, and I THINK it's 12" or more away from the turbo. I'm also using the stock SR SMIC with the recirc valve hooked up.
