2004 6.0 power problem

I have a 6.0 powerstroke and completely stock besides straight pipe and every now and then it has problems starting and when it does start from 0-20 it runs fine then it lags horribly till about 70 then it runs perfect like the turbo isnt spooling up and creating boost properly.. Im getting horrible fuel mileage and I can't figure out why it's doing it..it doesn't black smoke much at all and no white smoke... Help me

How long does it crank before it starts? When its "lagging" is it misfiring/running rough or just not making boost? Do you have a boost gauge in your cluster? If so, what is it reading?

Good to hear, that's a very common problem.
