After reading this thread and the other one that I started I don't understand something. If clamping the line should make the turbo boost with zero control say to even 50psi (exaggerating) why is it that when i clamp mine i can floor it through the entire powerband and have it hit a maximum of only 15psi?

you keep changing your theories. go read the other thread. we've all said the same thing before. Louis and i where taking about FACTORY wastegates and concerning the OP situation.

your wastegate is fully opening by the back pressure, your spring is tired and worn, simple. if you were using a tial that would be another scenario yes you could see boost as high as your turbo can produce

What's happening is your factory wastegate spring is weak and it's opening by itself. You will get flat boost because your turbo is huge! If your wastegate worked correctly, you should have seen more boost pressure.

because moroni944 believes that a boost spike on a pinched line is the same as sustaining 21psi.

Lindsey Racing dual port does not flow the same as the tial, are they both dual port yes, but the LR uses the stock lower casting with the valve configuration same as stock.

heres the difference champ. the tial pushes shut preventing exhaust flow from entering the wg exhaust chamber when it opens the valve is pulled into the body, which is the same direction as the exhaust is flowing.
on a stock one th exhaust is allowed to enter the chamber at all times. the valve is pulling up holding the pressure inside the chamber, when it opens the valve slides out and the flow of exhaust moves in the same direction its opening
this is why the tile mount opposite of the stock and lr.

I didn't mention that, or showed diagrams on how the factory wastegate works.
What tile? Floor tile?

The Tial and the LR dualports are different. Not to mention the diaphragm is different. The 2 ports on the diaphragm are oppisite to eachother
The LR the valve exits the ports while the tials valve goes into the port.
