Boost Cut, Random Power Lost, Wired Filter Sound

[Kaido_RR]

Hey,

On the weekend, i took of my turbo (a try to fit i new one but the new one didnt fit due to having the incorrect lines) so i put the old turbo back on.

Now i am having boost problems; When setting my boost to 0.8bar on my Profec A EBC,

The car accerlarted then i get boost cut, power kick back in, boost cut power kick back in, also i get alot of missing firing, random backfire (alot of black smoke out of the exhuast)

On top of that my airfilter doesnt sound the same under accerlation, same goes for my BOV;

My idle is also having problems, it wont hold at 900rpm it drops to about 500rpm and almost stalls then kicks back up again

I have check the following things

EBC< -All lines are connect right

-No air Leaks

FMIC<-All Pipes are connect right

-No air leaks

BOV<-Connect Correct

-No stalling related problems (i didnt have a problem with it before i change the turbo)

I have a feeling it might be AFM related on something to do with the pipe which connects the AFM to the turbo.

Does anyone have any idea?

The problems doesnt happen when i run stock boost or 0.5/0.6bar
