No Power When Moving From Standstill

Hi, I received Dodge Journey 2008 2.0 crd 4cyl Diesel engine with DPF . The car was on limp mode due to block dpf,we remove it from the car and we do dpf off and egr off,we clean also the intake from carbon. Now there is no limp mode ,but when u push the pedal to move from standstill u feel acceleration response delay for 5 seconds the it get normal power with high boost,but if u stop and u need to move again from zero u feel the Low power for some seconds. Air filter is new ,no faults code. Plz advise and help

I do not know if this has a variable geometry turbo or not but I have seen stuck vanes in a vgt do a similar thing. I don’t usually work on cars though. I know on the trucks there is a scan tool function to command the vanes to move and see if they actually do. When the vanes stick it is like you have a bigger turbo so it takes a long time to spool and build good pressure.

Arrrr the VW engine check the vacuum system to the TURBO make sure the electric solenoid is working ,and make sure vac is pulling 25 hg to see if the vac pump is working properly ,also check the waste gate is opening will have to suck this see if it moves as the dyfram can have a hole in it also the egr ,if the teeth stripped in the actuator motor but this normally bring up a code but these…
