I have the clutch shuddering problem and i know all about the service bulletin. I have 19,000 miles on the car, but im worried about them not covering it under warranty because of mods. I have a cat-back exhaust, APS bov, cold-air intake, and a Unichip w/ boost control. The Unichip has a plug and play harness on it so it can be taken out but im sort of confused on how to remove the Unichip and the boost control module that comes with it. Does anyone know if they might still cover it. I will be taking i to Huffines Subaru in Lewisville, Texas. Any advice would be appreciated.
