and have been told by stu its very laggy so i have taken it off and discovered that the 2wdmanifold its fitted to has 1 bolt left in it where the two pieces join each other and you can move the manifold sections and get a slight gap, there are also only 9 bolts holding the exhaust manifold to the head , the rest have fell out

am i right in thinkin this is the cause of my lag as the turbo is still new and has no cracks etc
