Turbonetics Deltagate Vs. Tial 35mm Wastegate

[gwong]

I'm replacing my Deltagate with a Tial Wastegate because I hear that the Tial wastegates are better in quality than the Deltagates.  I was using the Deltagate on my KA turbo, and every now and then when I look at my boost gauge, I would see it spike past the expected setting.  So hopefully, the Tial unit would reduce this problem.  Anyhow, I just wanted to see if anyone out there has done a similar swap or know of any actual experience with these two wastegates.
