No power after replacing Oil cooler

I recently replaced my oil cooler, I have no power whatsoever. Max boost is 3 psi. My wires going to the connector on the VGT was accidentally broke. I repaired that, even to the point of making my own Pigtail to reassure that I had a good connection. I tested the VGT solenoid for proper ohms, everything was good there. Pretty sure that I do not have any leaking pipes going to or from the Turbo. I don't really see the vanes on my turbo sticking as the turbo was working fine before I removed it. Any info would be great.

Unplug the pigtail does it make a difference in sound when running? Sounds to me like a typical exhaust leak

There is a different sound pitch when its plugged vs unplugged. I have another correctly running 6.0 here and I unplugged that one as well. Both sound very similar. That tells me that its working properly. Also I did a ohm test on both solenoids and wiring they are very close to each other. I could not feel any exhaust leak around the turbo or hear any leak.

Intercooler boot?, I'd almost bet it's an exhaust leak at the flange from flex pipe.

Intercooler boot would definitely do it but be so obvious. Can the OP hear a leak? Should be a damn substantial hissing sound if you're maxing 3psi.

If the op has a tuner put it on a high hp tune and put it in park and have someone step on the gas real quick to blow some soot. If you have an exhaust leak you will be sure to see the soot poof out... The op would def hear a leak if 3psi is all you can see

Problem solved!! Tracked down the MAP sensor hose, right above where it attached to the intake there was a crack in the hose. Cut out the bad section and problem solved making plenty of boost! This problem took me a couple of days to figure out. So glad its finally fixed.
