Still sounds like you hitting smoke limit as you ask for more torque it shoots off wile getting boost. Data log will tell it all if this is the case or it’s just a bug in the SW or are you running on a breakpoint the ECU needs to build a load of boost by the boost target setting in the ECU???? Or is it making loads of EGR as the NVT is almost shut complete before you going wroom??? More than 5D tuning is not an easy task.
