Car has no power at all

Got her started and let it warm up, got it out of the garage went down to the court and turned around on it's own power. Probably didn't go more than 10mph. Come to the drive way which is at a very slight hill, maybe 20* and the car wouldn't go up it. Wouldn't rev past 3k either. If I gave it full throttle with the clutch in the car would die, if i peddle the throttle it would get up to 3k and let out the clutch I was lucky to go 1/2". Only way I got the car up was by using just the clutch and no gas.
Took off the oil cap while it was running and there was a LOT of pressure coming out as well. All connections were cleaned, last owner put a new distributor cap and wires and the maf has been replaced as well. Where can I start to troubleshoot?
Spun the turbo by hand and it spins freely.

Cleaned the maf and no difference. Next I will try to unplug the maf and double check the wiring for spark plugs.
I found this pic, is this the correct order?

That pic is wrong, I looked in the manual that came with the car in the back seat, got it running smoother. I can get it to 4k rpm but that is it, still stalls if I push the gas down.
Here is a video, when the rpms drop its me pushing the gas

Direct link incase this doesn't work.

could it be the ECU? I've had 2 computers go ever and they both just acted weird.

Maybe I don't k ow anyone with a ecu to swap with though.

Does this car share the same computer with any other cars? Any chance a 1g ecu would work or can be made to work?
Won't get to drive it again until the weekend, pulled off the water pump and a/c compressor.

If you still have the 2.6, you should post on Starquestclub for help. They're pretty helpful with that stuff.

Or do you have a 4G6x?

Still got the stock 2.6 in there. Wish it had the 4g I would have no problem on that motor.
Ok figured out the first cat was clogged so I cut it off and welded up a exhaust tube straight down. Did a compression test and 1,3,4 are 110 and cyl 2 is 90.
Is 110 about average on this car? Or could it be the headgasket isn't sealed yet since it's pretty new? (last owner did it)
Took it for a ride and the turbo spools easily, and is pretty loud for such a small one. But the car still has no power, give it gas and it dies. I had to just use the clutch to get it back from down the street.
Pulled the plugs and they look like crap but still useable.
I'm lost.

I signed up on that forum and the admin never approved it and it won't even let me view the forum.This is the message I get

I tried the diagnostic port and all I think it has a bad o2 sensor, however shouldn't it still run with a bad 02?

Take it to SQC.

I have some spare 87 and 88 ECUs I could sell if you find out you need one.

Guess I'm screwed because i can't access SQC. Can you PM a mod over there for me?

Still can't get on the damn starquest club site.

Got the car to run, got new injector clips. Had a minor fuel leak out of the top oring on one injector, let the car warm up and it disappeared.

Now I don't know what to do. I am probably going to add a bov, and would love to lose this stupid maf but don't want to pay a lot for a gm maf.
