Full boost, no power?
Posted earlier and no one got back to me. My truck with a trailer makes full boost like instantly, but the truck doesnt seem to accelarate any faster and it causes the trans not to shift properly. Any ideas from anyone?

2005 F350 CC 4x4 Harley Davidson edition, 6.0, auto trans, head studs, head gaskets, egr delete, hpop upgrade, upgraded FICM with atlas 40, coolant filter, just cleaned the turbo and installed new unison ring, Silverline diesel duals, no cat, 3.5" downpipe
And yes I'm going off of the dash boost guage, I dont have a tuner yet. SCT Livewire TS is getting ordered tonight though.

boost leak? broken map sensor? goes from the pass side on a little bracket to intake manifold...broke one by accident when i was working on my uncles 6.0 and it caused 0 power..could hardly get the 550+trailer w/ bobcat moving. Replaced that and good to go, check that its cheap

MAP sensor is good, just checked. I don't know if it was just the wicked wind the other day but my truck could barely hold 60 mph with the dash boost gauge around 20-30 pounds. It just seemed like the truck was a dog with only 4000 lbs on the trailer.

1000 miles ago I suppose. I have maybe 1500 miles on the truck since head studs and head gaskets.

i would love to find the outcome. mine started doing this recently. it will redline then dump the boost back into the intake. i'm going to change my filters again and see if it helps. maybe fuel pump is on its way out.
