I have a 99 lightning 240k miles decided to clean intercooler. ended up breaking the mid plate after getting a wire hung in the back got another mid plate put it back together. and at wot I get 1-2 lbs of boost supercharger still whines loud. looked at boost actuator lever was up and when reved didnt move any thought maybe I got vaccume lines on wrong. so I swapped them started building boost but sputtered badly. and now it has a loud whistle any ideas to what my problem is ?
