Yesterday I got the chance to change my wastegate spring. It was orginally a 7-9lb spring boosting at 7-11 even twelve when I hit 7500rpms and above. Well I installed a 5-7lb spring with the nut completely off. Boost starts at 5psi then builds to 7psi around 5-6k. Once I hit 7k or above the boost jumps to 10. I do need a new gasket that goes in between the exhaust manifold and turbo. I just don't understand why I'm boosting so much even with a 5lb spring and a slight boost leak. If there is a boost leak I should have less boost than what I have. The weather has been kind warm, its been in the mid to high 30's and I still have boost spike. I'm thinking that the 60-1hifi pushes to much to the wastegate, therefore the wastegate not being able to handle the high amounts of gas release.
