Analyse Nanocom Values TD5

After a long layoff, I was finally able to move forward with my disco projects. I installed a large-volume intercooler, changed the MAF, the turbo, and the wastegate valve. It pulls well, but I still find it struggles to rev up. It blows a lot, and it feels like it's going full throttle from 2,500 rpm. I have trouble getting past 3,000 rpm, yet when I watch some videos, I see disco TD5 exceeding 4,000 rpm... I don't know if this is the norm; I don't know any other TD5 disco owners.

I was able to make a nanocom recording of a revving up on the highway.

If anyone has time to take a look and tell me if everything is okay with:

- RPM
- Coolant temperature
- Turbo boost pressure
- Cylinders
- Accelerator pedal

And is it normal for me to have an EGR reading even though I've disabled it?

Thanks for your contribution

Not being able to exceed 3000rpm is commonly fuel related i.e. a failing fuel pump or faulty regulator. Have you tested the fuel pressure ?

Nothing obviously wrong in those readings except that the coolant temp goes a bit higher than normal, if it's blowing black smoke i doubt it's underfuelled but there can be a leak along the air inlet/turbo circuit somewhere, some important things to clarify:
- is it Eu2 or Eu3 engine?
- manual or auto?
- what dimension tyres you have?
