limp home mode
Ford F350 S&B intake no other mods.
Turbo was farting under acceleration and turbo boost indicator was flopping to zero under load or high speeds so I sent it to the dealer. I just got my truck back from dealer needed ECM updated and now i can not get on the throttle long enough to reach 60 mph with out the limp home mode kicking in. This resets after restarting but what the hell is going on here.

ok so they didnt do anything with the turbo? you need to take it back ASAP before they tell you they cant do anything because you waited. whatever they did is most likely causing this, they didnt fix the problem. In all honesty, this sounds like a pcm issue. turning the key off and back on seems to reset it? thats because your pcm needs driving information before it can act and throw codes or lights. it cant know whats wrong until its driven through to a problem. OR the pcm is throwing into limp mode itself because it has the wrong information to compare with what it's actually reading.
does your turbo problem still exist? what else happens before it goes to limp mode?
