Air flow escaping at EGR Cooler connection to ex. Manifold

I believe there are EGR pressure sensors , however I have no codes related to that. what do you think? When I pulled the EGR crossover tube off while it was running it had LOTS of pressure behind it. Maybe EGR stuck?

Is this while engine is running?.

Is the engine de-mandated, or have any custom programming in it?... or everything is still in tact?. - YOur posts imply that everything is still in tact.

(non-deleted, factory programming)...
Those smaller engines have issues where the turbo will over-spool all the time, especially when the EGR cooler starts getting restrictive. they will also do it if the CAC is restrictive too (after-market unit, dusty, oily, etc). So will higher then normal exhaust pressures (partially clogged cans).

the turbo will also spool up higher than normal if the DPF is simply not warmed up all the way yet too.
