Default 7.3 PSD intercooler & intake boots

Developed a leak somewhere. Was told by the shop that did my front axle work that the upper & lower intake boots were leaking & was throwing codes to back it. Had no idiot lights at all on the dash. When its cold its like the bypass leaks until it warms up & then its fine. Recently when I start to move (still somewhat cold) I can almost feel no boost at all, pedal to the floor & barely moving. I let off & roll back into it & the turbo finally spools up & gets me going again. 1 of the upper intercooler boots in greasy & dirty, but the orange intake boots don't "look" to be leaking. Plan was to replace all 4 intercooler boots & clamps ($220 thru my brother at ford) & maybe do the orange intake boots as well. Anybody have thoughts on this? Ive been told there is a ceramic style boot that is much better to use & more durable than the hi pressure boots from stock. Between that & the rear driveshaft carrier bearing support & 3 u-joints I need to replace, Im going to be into some money here.

Having boost leaks will not throw any codes...
If you end up needing new boots I'd suggest the ones offered by Riffraff Diesel, great prices and service. I'd start by building a boost leak detector and see if and where you have any leaks.
Not sure what you mean about "when it's cold its like the bypass leaks"?

DieselSite.Com Makes Some That You Will Never Have To Replace Again. Good To 100 psi, And Oil Will Not Dissolve them. Ive Got Them On Both My 7.3'S And Several Of My Customers. About $200 For All 6. I Think They Are The Same as Riffraff...

When the truck is cold or been running for a few mins & I start to drive off, sounds like a blow off valve thats stuck open until I roll on the throttle then it goes away. After it warms up it disappears completely. Like a valve is stuck open for a little bit.

What you're hearing is the exhaust backpressure valve doing it's thing. It's a common issue on the 7.3's. They activate in cold temps to help the engine warm up. It's not supposed to shut while driving but it is known to happen.
There is a 2 wire connection on the turbo pedestal in the front, unplug it and the valve will default to open and you won't have that issue anymore.

But it will take FOREVER to warm up.

you can also warp the backpressure valve and it will cause it to stick and it won't let your turbo build boost. It might be what you have going on here.

It's a 7.3... they take forever to warm up no matter what! You could always wire it to a switch so it will only close when you want it to.

Never heard of that issue before but I suppose it's possible if you get it hot enough.

Just ask me how I know, with 20,000 pounds behind you pulling over 4th of July pass seems to get it hot enough.

This will work and may be worth looking into. There is a way to wire the "preheat" valve to make it work as an exhaust brake also. Really simple on a manual, a little more involved on an automatic as it requires a relay to lock up the torque convertor also.
