If you want to run more boost than your stock waste-gate actuator spring can handle or you want to reduce dreaded boost sag, you need a boost controller! Mechanical controllers are very easy to make yourself, often from stuff you may already have around the garage. I'll show you how to make one but more importantly how to dial it in SAFELY.
Stuff to find/get (usually from the plumbing or air tools aisle of a hardware store):
1/4" T fitting
1/4" NPT hose barb fittings (need 2) - amzn.to/34u6Ypi (set is enough for two controllers)
1/4" NPT adapter fitting (other side doesn't matter since we'll cut it off)
1/4" ball bearing - amzn.to/3mjWbUW (I couldn't find this so I just ordered it -- you can break open an old caster from a chair or wheel from a skateboard)
Small spring -- I think this was from a large ink pen, lol
M10x1.5x50mm bolt (or similar, just needs to fit in the T fitting) - hardware store
M10x1.5 nut (used as a jam nut, match the bolt you choose)
1/4" rubber hose (a foot or two depending on where you mount the controller) amzn.to/3mjvgso (this is for a LOT but it's cheap -- I replaced all my vacuum hose on the car)
Tools:
Some sort tap -- I used an M10 tap but 5/16ths or 3/8 will work too. amzn.to/3osS2A3 (I have this one...not expensive and covers a tons of sizes, super useful for fixing rusty threads or cross threads. There are also cheaper ones for like $20.)

Thanks for the vid! Cleared up some questions I had about waste gates and how they work!

Pressure regulators often will have a washer that sits between the adjustment screw and the spring to prevent binding and spring shift. It would also stabilize the seat pressure of the ball bearing with a consistent vertical downforce.Edit: I enjoy your content and thanks for all the MS tuning tips a few months back.

Thanks, good tip! My spring seemed to seat fairly well on the bolt but now that you mention it, I may go back in and add a washer like you suggest. Easy insurance.

BTW, these mazada things are set up unique arnt they? Is that the water pump sticking out front?

No I think you mean the water neck...usually that's connected to the upper radiator hose. But I have a coolant reroute so I just have a plate over it to block it off. Next time I have the timing cover off, I'll probably remove the whole neck to clean it up.

Put tape on those threads and the bolt to jambed nut setup will be more forgiving when adjusting. You knownwhat I'm saying? It will have some resistance for you while your trying to set the angle of the dangle....yee yee.
