I have a 2000 f250. I have had it for about 3 months now. Its been pretty good truck for me, but a couple of weeks ago the turbo or something is not working right... its either boosting before it shifts or after kinda hard to tell will get up to about 2800 rpm and either shift/boost rpms go down to about 2000 then it will do it again at about 2500... just doesn't feel right... And some days it will run fine.

 

huh... Do you mean that it feels like its losing all its boost before it shift?

 

Yeah maybe that would some it up better sometimes it does boost and next time not so much and my rpm will not kick down all the way

 

can you elaborate some more?
