Why, thank you. It looks decent from about 10-20 feet away. lol

The car has developed what feels like fuel cut at about 4k. Drives around perfect until I start going more than 50% throttle and the boost goes above 12 psi.

I've checked:

-Plugs
-Mafs
-fuel system for leaks
-Boost leaks (none)

On my datalogger the only thing that looks fishy to me is the injector duty cycles go from 20-30% all the way to 80 something percent right before it cuts out.

As of right now, I want to say the pump might be taking a crap? It's an evo 9 unit that I replaced in the winter time a couple weeks before swapping motors.

So I think I've found the problem. I took the cop setup off a few days back to inspect things and ever since it's been on like 3 cylinders. Well I took the cop back off today to check the plugs, put it back on and it ran fine till i touched the gas again. Then it was missing. I took the cop off and sure enough, one of the wires were pulled out of the stock plug on the cop side of things.

I crimped it so it's hardwired for now to get me to work. When I get to work, I'll solder it up until I find a stock plug again.

Well it drove fine on the way to work but still cut out under load. Pulled it inside the shop right away and soldered the 3 wires up. Pulled it out of the garage and it was back to missing again. On my lunch break I took it home and would only run right if it was between 2500 and 4k. Anywhere else in the rpm range and it would be on 3 cylinders.

I know for sure the number one cylinder isn't firing for whatever reason because I can cut the number one injector on my datalogger and it doesn't change the 3 cylinder running. I'm waiting for some motivation to hit me today and get my ass outside to mess with it some more. I have a stock coil pack and wires I picked up from Twack, just waiting for said motivation...
