wastegate closes while driving

We have a 2000 f350 at work and I have noticed that the wastegate (?)is closing while we drive. When you let off the throttle then get back on it slightly you can feel a lag and you can hear it surging and then it will open and the truck runs fine. Is this normal? If not what is the fix? I've only noticed it since it has been cold out.

Re: wastegate closes while driving

Not wastegate. It is the Exhaust Back Pressure Valve EBPV doing its job... perhaps not properly but none the less... my 2000 dually and Excursion do not activate like that but my early '99 does make hiss while driving at times.... part of the early/late diffrences.

I knew it wasnt the wastegate but couldn't remember the correct name. I can't imagine that is good for it. Is there an adjustment? I would think it may be killing the fuel economy.

There is no adjustment, but you can delete it if you want.

The valve is located in the turbo pedestal and the flapper is located in the exhaust outlet on the turbo.
