I've got stock Garrett and I'm considering upgraded turbo and TU exhaust manifold. Would this require a change in ecu calibration {currently run TU cal}or could I simply raise my fuel pressure and be good to go?

What turbo?
You could get away with. You can always do the safe thing and just take it easy, watching your guages, if lean, add some more fuel pressure. As you know, you should get a new cal but then, we are cheap sometimes,

Who's doing cals these days?
I'm undecided on which turbo...super 60 or 50 trim. It'd be going in my 2.5 Lebaron for now. I'm getting too much oil on the intake side so times coming to make a change.

things that affect headflow and overall flow of the engine require a cal to be changed.... the larger and more free flowing exhaust side of the turbo will affect the fuel curve more than the compressor side. so yeah, the cal should be changed... at least the pumping effeciency should be tweaked.
