I just put in a new turbo (SPS62) and now im wondering why when i stand on the brake and throttle i have a 15# boost limit. I can watch the boost gauge and when it starts coming on hard at just below 15# it starts to defuel and stays at 15#. Im running my Edge Comp Drag on 5X5. When im not standing on the brake and moving down the road it will go up to 45# of boost. How can i stop the defueling? Thanks for the help!
