no low down power
pretty much all those things will cause an error code to have been logged. The ECU knows what values to expect from most of it's inputs at various engine speeds/loads etc. It is not just component failures that are logged, but any out of band readings and if they were the cause of the problem it would be recorded.
When accelerating the Fuel Control Actuator on the injection pump increases the fuel pressure and the injectors open for a longer time to allow more fuel in. You need to get someone with a decent automotive oscilloscope to look at the signals to the FCA and the readings from the fuel rail pressure at the same time to confirm that pressure is increasing quickly enough. It's very unlikely for the electrical signals to the injectors being at fault.
At low revs the turbo won't have spooled up and will be providing very little, if any boost. Even at high revs when the engine is not loaded there is very little boost.
Other things to check are the live data from the sensors. Does the manifold pressure look right?, does the MAF reading look good?, what gear is the gearbox really in? (if an auto) what does the engine think the air temp and pressure are? actual vs desired fuel pressure and so on.
Having a second chrysler to compare to would be useful.
If I ever get a bit of free time I really ought to collect a set of "standard" readings from ours.

update guys I changed the turbo yesterday , took me 6 hours , but I still have the problem , I think its time to look at the clutch switch now , I have been told it could be faulty and not telling the ecu that I have release the clutch until I get to around 1500 revs then it will go , I was also told if my cruise control works it wont be that switch , but my cruise control works fine so I don't know which way to turn now , apart from taking injectors out and getting them tested by another company , not the one I got them reckoned at , see what they say , I have noticed when I first start it up , for about 5 or so seconds it splutters as if there is too much fuel
As far as I'm aware the clutch switch just interrupts the voltage to the starter coil unless the clutch is compressed.
I take it you checked the vacuum line for operating Turbo as there are instances of it holing by rubbing.
But this spluttering on startup is something different.

would blanking the egr valve off effect the vacuum , and is the a diagram of the vaccum pip layout because I could have mine the wrong way and not know , because the bloke who had the car before me messed about with it trying to get the injectors out so they could be wrong
