Hi all. My first time here. I've had the dpf gutted out, egr valve blanked, adblue deleted. All have been remapped from ecu. Since then the engine is sometimes making noise, like a rumble then a click. I noticed the turbo actuator arm moves up and down whenever it makes that noise. And when I turn engine off, I hear 1 or 2 clicking noise. Also when I drive, the car jerks everytime i accelerate or decelerate. Has anyone else has these problems after a remap? What needs doing? Thanks. 

What remap? Was it on a rolling road or just done stationary. If it's the latter then you need to get it on a rolling road. Darkside developments, Celtic tuning or Revo should be able to help.
