Ive been driving the last week with my wastegate closed under any type of driving. Its set with a 4 pound spring. I use to have the vacuum line going from the turbo outlet to wastegate and 1 time it opened and stayed open at 4psi. After that for some reason it stayed closed. I changed the vacuum source to intake manifold vacuum and now it stayy open at vacuum(idle, ect). What the hell is going on, Im really trying to get this problem fixed. Thanks for any help.
