Hey Annie! You didn't forget to mention rebuild of turbo. But maybe your description of noise needs better splainin', eh Lucy. Is it mooing or a grinding. Did you check the turbo for free spin before resetting it? Cause a grinding would mean the turbo fins are hitting the housing, not good! I myself have often wondered hat all the mooing is about, so I've learned from your question. At least now I can stop looking over my shoulder wondering if I'm going to get trampled by the ensuing stampede under my hood. Also how much boost are you showing in regards to less power and check your dist timing, 12 degrees. Good Luck Gus.
