Strange...I have had the same Tial MV-S waste gate on my car for 3 years now hooked up to the IM, and not a single issue.
If you hook it up to the compressor cover, the boost will fall off in the upper RPM range. This is due to pressure drops across the entire system.
On the build...I am now working in the waste gates, things are looking good so far.
