probably a kid high in bath salts, I got to get some sleep. Let someone else teach this guy in a proper english I give up, I have a feeling mahony is not playing with a full deck of cards

CAUTION!
Use extreme caution when driving the car with the actuating line clamped off. The overboost protection system is defeated by clamping the line. If the charging system is intact, you can overboost the engine and cause extensive damage.

Buddy. I don't think YOU understand correctly.
The turbo back pressure (which is in the coressover pipe) is MORE then what is in the intake manifold.
That back pressure pushes the wastegate valve open. When there's a small about of boost. The valve opens slightly. Then the turbo spools up more, the valve will open all the way.
THIS IS ON IT'S OWN BECAUSE THE TURBO BACK PRESSURE IS PUSHING THE VALVE OPEN.
Now, The boost line that goes to the wastegate works WITH the backpressure. NOT AGAINST. If there's boost going into the wastegate from the boost line. It will make it EASIER FOR THE WASTEGATE TO OPEN
The sooner and easier the wastegate opens, the harder for the turbo is to spin which creates less boost.

therefore ill repeat, running a direct line to the wastegate will lower boost, and clamping this line will raise boost

In different weather, you car will either overboost or boost less then the desired pressure.
When it's cold, expect your car to hit 1-2 even 3 psi more then you desired. This is where the KLR steps in and says "ok to much boost, time to bleed more pressure into the wastegate to keep the engine safe"
you can overboost
and
you will overboost
have 2 different meanings.
you can means you might but probably not
you will mean you will.
I'm out. I'm tired of explaining this to you. you simply don't listen. I've build engines before, I've ripped apart my whole 944 turbo before.
I build my whole engine my self. including the custom exhaust and modified turbo mounts and modified crossover pipes.
I've bench tested my wastegate many times
I've ran my wastegate in 3 different port modes! 3 different ways in a dual port wastegate!! can you believe that?
And no you don't "Win"
because if you think you "win" go buy a 100% stock 944 turbo and try boosting it.

It's a caution because you have 0 boost control with the KLR. saying you may hit overboost.

We've been explaining that to you the whole time
Running a direct line will lower your boost to probably 5 psi. (depends on the turbo)
Blocking the line will give you wastegate pressure. In the case of a STOCK wastegate it's 10psi
In the original post, it's around 15psi because of the shims
That's it. I'm gone.

The sooner and easier the wastegate opens, the harder for the turbo is to spin which creates less boost.

yeah it runs probably 5 psi because thats the spring pressure maxed out. clamping the line will cause you to max out your boost gauge, give it a try. ive done this test and confirmed it.

go clamp your boost line and watch the boost gauge max out, enjoy
