Review on DNA Motoring WG TS 50MM BK External Wastegate by Jeremy Bradford

Upon inspection of the interior prior to use it was found to be filled with metal shavings and sharp points which could damage the diaphragm. I cleaned it and sawed off the sharp spots. I also put o-rings on the three internal main bolts and some thread sealant to better seal the lower chamber of the diaphragm to prevent leakage there (testing with a bike pump, it leaks heavily out of the box and the standard o-rings were torn). I lubricated the valve stem and it seems to be working fine on my bench. For the price and after some cleaning it should be fine but I'm not sure I can trust it for long term heavy use.
