The issue wasn't the wastegate itself... The issue I had was the 1 bar spring setup, was actually allowing my car to boost to almost 2 bar haha... Removed the inner spring and just left the outer 11psi spring in, and now it seems to be holding about 18 psi (gotta datalog it to be exact)... Setup is just very efficient... Should be fine for now with the single gate... I would eventually like to do a twin scroll/top mount setup, but thats probably a ways out... I think what I have for now is plenty, and should make for pretty good results...
