no spool???
 

I have an 01 F250 which doesn't seem to be spooling turbo or building any boost if it is spooling. (He truck does have high miles. I am wondering where should I start to fix this problem???

check all your intercooler boots and pipes, also your intake manifold and the boots on it, and the V-band clam on the back of the turbo, and hows your air filter look?

The filter is dirty

clean or put in a new filter and check the intercooler tubes.

ok if its the washable kind clean it, if not go buy a new one, then check your intercooler pipes and boots, v band clamp on turbo, and the intake manifold and the boots on it too

Well I know turbo is spooling but no boost. I was wondering if the wastegate could be stuck open? I checked the boots and they all looked and felt good. All were tight to.

Do you have a gauge on it? What boost numbers are you seeing at WOT?

There is no gauge on the truck. We were told to replace wastegate that it wasn't working.it is dumping all pressure before it can build

Do you have actual numbers?

If not, you're chasing your tail on GUESSING that you have no "spool".
