New to fords - 7.3 NO POWER

So, i bought this 1999 F350 not running. the previous owner said it overheated and blew up.

I replaced the CPS and then found out the ICP sensor was missing, as i dumped a ton of oil on the ground. lol. i put a new ICP on and cleaned out the fuel filter. I eventually got it running, but it's WAY down on power.

there is no smoke. i was thinking the old fuel was junk, so i drained the tank with a hose and filled with 15 gallons of fresh diesel. also changed the fuel filter for a new one.

if you're driving it, floored, it'll take ~10 seconds to reach ~2500rpm. you can hear the turbo screaming and the check engine light will come on.... as soon as you let off the gas the light goes out.

what should my next move be?
thanks in advance!

Since the SES light came on, the very first thing should be to get it scanned to see what the codes are. That should get you started in the right direction.

Sounds like you blew a boot off. Check for a boost leak.

The torque app for android with a blue tooth obd2 adaptor. It should be around $20-30. Search around here and you will find a lot of info on it.

i pulled the valve covers and i think the drivers side has slipped out a little, maybe a little over 1/16" .... i wasn't really sure what i was looking at though and ended up disconnecting it before trying to push it together.

the passenger side had slipped about 1/8"

both connectors fell apart as soon as i touched the clip though, so i guess i need new VC gaskets.
