I'm not an expert but it looks like your pump is sending too much fuel to the engine. Maybe you purchased a pump that is for a bigger engine or you purchased a performance fuel pump?

I believe there to be many things that can coz this black smoke

And thing is you gone run around and spend money by tryna figure out the issue.

I am no expert but if any1 els seconds me then i would say get some1 with VCDS to check the sensors and to check for errors .
If the person is a merchanic also to check timing
I changed sensors back and forth just to find out it was timing.

Hope you come right

Cheers

I dont see how a more higher pressure pump can coz issues

There is a FPR regulating the pressure and release fuel if there is too much pressure back to the tank.

The injectors also only open and close on comand of the cpu so still cant have a issue.

I can be wrong
