ok so i got out of my car to see what could be wrong and niticed all the exhaust was comiing out of my ebay wastegate at idle. so i biult i blockoff plate. but i know it wont build boost if the car is sputtering like it is. it ran fine and on all 4 cyl before i put the stuff on. what could the sputtering problem be? im guessing fuel mixute. maybe to much. lol. i know its to much. but could that be it?
