I’m currently driving a bog standard 2003 td5 auto. Well underpowered is an understatement. I’ve seen ferrets pull away quicker. What would give me more power cheaply and easily without going down the remapping Avenue. I’ve heard different arguments over egr blanking but if there any advise from people that have done any mods I’ll be glad to listen.

For a start, do you know if it is all working correctly?

+1^^^ it might have some management or fuel supply issue... air and fuel filetrs are new? , unplug the MAF's electrical connector and drive it so for test, also if it still has EGR(which you should bin) clean the MAP sensor cos it's full of gunk, make sure that the wastegate rod is not sticking, the catalyst should go away cos if it's clogged it restricts power big time

anyway you must diagnose it first cos it's not supposed to be so underpowered as you describe it

Just get it mapped mick at dynochips is your man you can do all the rest but getting it chipped is the only way

Discoverys are heavy old lumps and the auto box saps power too... Decat and a good remap you won't look back

Remap worth doing but only after it's running as it should as standard, minus EGR and cat as @sierrafery and @neilly have said

+1^^^...off course, if it has unfixed management or fuelling issues or restriction on the intake/exhaust no remap would help

I’ve checked the maf sensor or air flow meter all clean. All seems to be running as it should. Don’t get me wrong she goes ok but just seems slow on the pulling away. Once she moving she will cruise at 80ish no bother. She just needs a bit more bottom end grunt. I will order a egr blanker tonight. Are any better than another? I’ve got a cat free pipe somewhere so I’ll chuck that in at the weekend. I’ll also check the injector loom for oil ingress.

Have you had it on live running diagnostics?

and got a record of it?

A common "fault" can be that you're not giving it enough loud pedal... I suffered the same issue when I first got my TD5.

Tis true, they do.
But make sure they are working correctly before spending money on it.

^^^^^^^^^^^^ What he said ... Don't go spending money trying to find a problem that doesn't exist!

This. In particular, forget about trying to drive a TD5 auto "like a diesel" (i.e. with lowish but torquey revs). You can use way more revs than you might think, and they'll respond well. Which is odd for a diesel, but there you go - they're odd vehicles all round in their own way.

believe me the fact that it's clean is irrelevant as long as you didnt connect a tester to see the inputs

If I disconnect the wiring what will happen if it’s fecked.

Removal of the EGR isn't likely to produce that much of an improvement in performance, unless it's very dirty and restricting the airflow from the outlet of the intercooler to the inlet manifold. In my opinion, the main reason for removing it is to feed the engine with clean fresh air not already burnt fumes.
The main reasons for the EGR to get messed up would be either dirty oily exhaust fumes being let in as part of the job of the EGR or worse than that oil getting into and then out of the turbo, which is not good, at all.
Some people say that you should wash out the intercooler at the same time as removing the EGR, but provided the air filters are serviced regularly and the turbo is clean, there shouldn't be any real need.
If the EGR is dirty then you should really wash out the inlet manifold as well and clean the MAP sensor too.
