lower boost?

[protegejustin19]

Is it possible to adjust the stock wastegate acuator to run lower boost like 5 psi?

Why would you want to lower boost?

I believe it's tial that you can get a 4.5 psi spring for

The stock WGA has a threaded arm that you can shorten to lower the boost pressure.

because my car has high milage and i want to make sure s*** wont break at 5 psi? and to lower it i would tighten it to where it will pull the arm closer to the actuator for less boost or is it the other way around

 

[tweety2300]

You could just pull the turbo off if your that worried. Turbo won't spool up if your not hard on it

You shorten the WGA arm, whichever way that turns it and makes the arm shorter will lower the boost.

ok thats how i thought you did it is there a certain milage you replace the actuator or just when you start getting boost spikes and when you blow into the line and air can get threw you should replace it?

The longer the WGA arm is the lower yout boost will be.. the shorter it is the higher it will be because your putting more preload onto it.

Putting less tension on the spring (longer rod) will yield a lower boost, but be aware, if you do not have the gate sprung closed(preload), your boost will spike and act weird(also it will probably take longer to spool).

I wouldn't worry about replacing it, unless it rips, at that point Mazda was so nice to us, and gave us FUEL CUT

im not running the msp ecu so do i still have fuel cut?
