Have you tried disconnecting the wastegate to see what happens. What kind of exhaust are you running, could there be a restriction in it that you didn't have in the Dodge? I once had a muffler that collapsed inside, created a number of issues and took me a while to figure it out.

wastegate wasnt even hooked up with a hose to the compressor housing since i did the conversion, exhaust is a 4" downpipe to 5in epipe to stacks actually have 5in elbow to the stacks in the ford were i had 4in in the dodge. i noticed my motor torqued when i did the dyno and its not level noticed the wategate head is resting on the frame raill not sure if thats the culprit but will re align the motor this weekend

low boost with alot of fuel= heat aluminm melts around 1200* your pistons are aluminum when your towing temps excede 1200 when towing heavy up a grade if your not at full boost of what your turbo can produce

as for the turbo being shot that is very unlikely because it ran great in the dodge i threw caps on the turbo while it sat in my shop and then threw it in the ford so my guess is wastegate

i put an aftermarket manifold on a truck for my brother and the machineing looked horrible so i took a carbide bur inside of the manifold and smoothed off all on the spots where it was machined and a couple other spots that were tight going out to the turbo then took cartrige rools where i cut with the bur to make it realy smooth,

with a stock manifold i would imagine you could hog it out a bunch and make it flow better

ok here is a picture of why the motor was unlevel and the wastegate head was smacshed against the frame but wired the wastegate closed and same problem here is the exhaust manifold i am running it is off my grader since the stock one would fit with the 4in down pipe

Grab an hx40? Drop the injectors even more? Exhaust manifold? Down pipe?
