The only thing I can figure is that I think I may have over tightened the Compressor Nut on both Turbos. The blow-off valve not is working when I let off the accelerator at high rpm. Probably because of no boost.

decided to ship my Twins last week to Turbo City after numerous attempts (took them off/on 7 times) to diagnose my primary turbo whine failed. Instructions were given to TC to disassemble all the components and to inspect for damage of all the turbo kit components I installed. I also wanted TC to balance both sets of turbo wheels/shafts.

******* screw that held the primary turbos propeler fell off and ate the damn wheel. Oil everywhere, huge smoke behind me like from that game spy hunter. I don't know what to do now. I'm so pissed and hurt and broke.

I found the nut. It was just sitting there in front of the wheel. The front wheel was chewed up and the rear wheel was in the downipipe.
