its all hooked up the same as it was before the pipes.. i had the boost control before i put on the pipes.. i thought it was because my new turbo outlet elbow didnt have the stock boost control nipple on it, then i drilled a hole and put a vacuum hose connector in it and pluged the vacuum hose back in it. im realy confused on why its doing this, i am trying to stay at 15 psi.. thats what i usually run without probs
thanks
