Can someone look at my log and tell me if anything is wrong?

I have had a problem with my car for the last 3 months without any luck diagnosing it, even jabbasport failed.
I have a lack of power above 2000rpm, due to jabbasport not being able to find anything after an hour and a half of data logs they told me to see a diesel specialist

Looking at a previous log i done does my injector for cylinder 2 or 3 seem faulty? i have cyl 1 and 4 reading a constant 0.75, cyl 3 reading -1.79 but then cyl reading 0.24
just seems that there is no pattern between cyl 2 and 3

Any help will be much appreciated

I have had a mate that does diagnostics look at it and he didnt know, i have a thread on here with many logs but no answers from anyone. I aint had the time to take it anywhere else due to my job and where im working at the moment. Its booked into a diesel specialist for tuesday but if it is an injector they wont pick anything up unless they remove them and fit them to a test bench. i have got a cylinder head on its way off ebay complete with injectors, i am tempted to get them injectors tested and if all is ok just change them all, saves them testing the rest of the system which is costing me £85 and i can remove them and just get them to fit them
