And what you have heard is absolutely right - mine failed at 1000 miles on a stage 3- tune they started whistling after 100 miles
By fail I mean both bearings/seals just couldn't hold up and were dripping oil (small puddles in inlets and IC hoses)
I modified mine right away to fix http://www.audizine.com/forum/showth...oost-Creep-FTL
Ported the exhaust wastegate holes and adjusted the lifter arm lengths so that they would open like the OEM one does
Replaced the chra's with new ones built and balanced by BAE - so far so good, no whistle, no problems,
Total was 1100$
