i finished the installation of my turbos (dp broken studs problem)...i installed 2 k&n air filters and let loose the other hoses ( bov, air pump...) + 3"catback + 3"dp.
Then i start the car, smoke comming from above the turbos, maybe from the new gaskets, drive around for 10min then i accelerate a little and around 3500rpm a sudden big bog, the rpm dropped and impossible to accelerate. It did it twice then i stopped the car.
So you think its because of my intake modification? A possible vaccum problem?

 

Were you boosting? You might have made the car go into safe mode.. Stock computer?

 

i didnt check the boost yet....and yes i have the stock computer.
