Cyborg upgraded stock Turbocharger system

I do not sale these wastegates for any kind of profit. Both are just as easy to work with as the other. The tial MVS does offer one thing, and that's much faster shipping time. But other wise, I'm un-bias. The tial has some advantages and I'll go over them in a bit. But for now... Water bucket test.
I started with a brand new tial wastegate purchased by me for a customer from an authorized tial retailer.
I did not modify the tial wastegate in any way at all. It had been opened up to inspect the diaphragm and spring cup. This is how it tested....

This test shows the tial fittings are sealed tight WITHOUT any sealant on the plugs at all. The diaphragm its self also seals better.... But it has a flaw, and honestly:... Its an issue. Not that the wastegate won't work, its just... It should be sealed. The tial valve leaks at the valve seal/guide. The effect this will have is.... The 20-40-60psi that our exhaust manifold/turbine housing can see, can/will leak into the pressure camber, which will push the spring up and bleed off exhaust pressure before its supposed to. The one catch about this maybe that with heat, the valve may swell and seal its self at a higher temp, but it should not leak at any temp in my opinion.

This is the same test, same pressure. This is a knock-off valve fresh out of the box. The one thing I did do, was put sealant on the port plugs because they have already shown to leak, obvious in the video, I didn't put enough sealant on them or let the sealant sit long enough, lol. But the big thing, it doesn't leak anywhere else, just the fittings. The valve seal/guide does not leak at all. This is the 2nd knock-off I've tested like this. The diaphragm does bleed a little air out of the top that the tial does not.
I may as well go over some differences since I have a minute...
Real tial
Knock off tial
Real MVS tial ( notice the gap between the chamber and the base plate)
Knock off valve ( notice the chamber is flat on the base plate )
Tial V-band clamps. These easily a higher quality clamp.
The knock off clamps are def not as good. Sorry.
Tial nipple fittings with silver crush washers. Work great.
Knock-off nipples with copper washers. Recommend sealant on threads and maybe a little on the washers, tial also better, but these work with some love.
Valves next to each others. Ummm... Tial comes cleaner, lol.
Tial spring cup and diaphragm. If you can tell, its high quality. 4 set screws with thread locker.
Knock off cup and diaphragm. Not the worst, but it leaks a tiny bit and doesn't seem as high quality. 3 set screws without thread locker.
Double roll pins on tial clamps
Single roll pins on knock-off
Maybe one looks better quality to you???
Incase you missed the previous video/post, this is a knock-off I did seal the fittings on (correctly, lol )

This is meant to inform, not pick one over the other. I think either valve will do the job with a correct pre-load spring setup. We are still testing and if any new and proven results happen, then I'll do my best to inform. Hope this info can help
