Boostcontroler problem
 

Hi, can u help I buy cheap boostcontroler from ebay, try to put ot but the arow on pic was point at other way(find out later). Try and reverse those two lines from turbine to wastgate.And now the blow off valve dont work and all and the wush sound comes from turbo inlet insted of blow off. Remove the boostcontroler and its all the same.And boost is now weak the car wont accelarate like before this stupid controler.Only get 51 code but that code was there before and car was boosting normaly just before this instalation,now there is no power. And for the record I installed the aftermarket fuel pressure regulator.Maybe its some problem with turbine dont know,please help.I will take a picture of my build tomorow if that helps

I know some guys are very pleased with the GReddy Profec-B.
