This worked great with a K&N filter and you notice the difference right away . You need to go to Premium gas 93 octane and the ECu in Sport mode shifts tighter . I cut out the mid pipe and put in a set of Denso Racing plugs gapped at .026 . Raced 2 5.0 stick cars and held them till 4 gear .Got them out of the hole with the auto in sport mode and by 3rd have a car length but 4th they catch me . They cant believe a Turbo is that quick and when I tell them I am still Drag Racing at 61 they laughed!
