Unable to raise over 23 lbs of boost.....

[psmvchaser]

I have a PTE54 turbo with internal wastegate and 3" dp. Basically a stock engine. I have a custom chip.

My problem is that no matter what I do, I cannot get over 23 lbs of boost. I have tried 3 different boost controlllers and I have tightened the wastegate rod, but it still doesn't go higher. I was hoping to get 25 lbs atleast. I get basically no knock at 23 lbs.

I am guessing the problem must lie in the wastegate? I don't know much about wastegates other then what their main function is and how to adjust them. I've never taken one apart or seen any of the individual parts and how they work.

Does anybody have any suggestions or ideas for me on a possible solution?

How much did you tighten up the wastgate rod? With a PTE high boost unit I could get 20-22psi with just tighting up the rod.

do you have a std or high pressure actuator. tighten the rod and or get the high press actuator.

Unhook the boost line from the wastegate, that will probably get you your 25lbs :tup: :tup:

Just keep it at 23psi.
