Need Help With Turbo Diagnosis

[nitsuj08]

Still boost used to be higher.

It is now slower than the ole 92 7.3 idi non-turbo.

Which is supposed to put out 185 hp.

My boost goes higher too when I have the actuator enabled.

Enabled:32-35psi
Disable: 23-26psi

The actuator could be sticking like @AK Bob said, or veins could be sticking(is that possible?) or the actuator could be on its last leg.

Can take turbo off, remove actuator and clean.

Maybe go a step further disassemble the turbo case and clean the veins too?

How does all the intercooler piping look?

Nice and tight fittings.

Possible boost leak?

It is possible and somewhat common.

I don't believe that carbon build up is the issue in my case simply because I can hear the result of the turbo going through the full range of motion.

That isn't to say that the exhaust may be carbon restricted and causing these issues.

I guess that could happen.

Intercooler piping is tidy and clean.

Has never been disassembled either.

If you are dead set on running the stock turbo, I'd be looking at a new actuator and nozzle and unison ring setup.

I just did that in 2013 very recently.

Actually, the wife said compounds, fuel, and head work.

I'm a lucky man!
