I got this by putting a sports exhaust on it. Improved fuel consumption too. But, yep, it did have to be bought and I fitted it. Stainless though so should last.

Thanks but I was not 'messing around' with it, I was following a tried and tested method which works well and many Defender owners do this. The steps were taken from a renowned Land Rover expert - It's nothing new. When these vehicles were built they weren't really set to maximum performance but I am very aware of any possible pitfalls like head gaskets, overheating and the like so I am not 'really worried' at all. I just want to know if anyone else had issues after mods during MOTs, that's all. The pump, injectors and timing are fine. If I wanted it reset I could easily put it back myself to what it was but thank you for your time.
Thanks. I am aware that it's unburnt fuel and on diesels it's not uncommon. I have fiddled with the settings but haven't gone overboard like altering the main fuel screw setting. As I said, I wanted some feedback if anyone ever had any MOT issues after that modification to the pump. Thanks again.
I have messed around with mine many times over the years, always a juggle to get power and little smoke.
Always passes the mot, trick is to remove the sticker under the bonnet, no sticker means mot man has to use max figures (3 I think?) rather than the lower ones on the sticker.
What sticker is that? I don't think I have one. Won't they use set parameters rather than check the stickers? I don't know, just guessing. At least I don't have one but that's an interesting point. Cheers
Well I guess it all depends on your mot tester, put it in for a mot and see what happens or book it in for a emissions test. That is the only way you will get a real answer.

Excessive smoke, at least for road use. But you do get more power. Anyone who says you don't gain with smoke has not done an testing. All you have to do is look at diesels in motorsport where they aren't regulated to not smoke.
e.g.
At this level and cost point, these people know what they are doing....... lots and lots of smoke.
If it didn't help or make more power, they wouldn't do it would they.
Old crap like we have they use the sticker under the bonnet to set their smoke meter.
I have a pic I will find and post up, mine was white approx 30mm square with blakc letters saying something like 1.30.
Never seen anything like that. I definitely haven't got one on mine. Or any of those other nmbers. You learn something every day!!

Take it somewhere else. My local garage is a Land Rover specialist and they never do this to old Land Rovers when they MOT them.
I will ask them so maybe they don't. Maybe that will just apply to newer engines. Thanks.

Not sure if pumps are the same
Thank's for the link but mine's a 300tdi. I spent a long time watching videos andb learning how to do this mod which would give me a bit more power, thought carefully about anything I did. I know all the possible fitfalls and what can be done to mitigate them too. Yes, all the pumps on the 300tdi of that year use the same pump as far as I know but any work I do I always make sure they are talking about the same pump as I have. Everything is fine with what I have done so far along with the necessary gauges. I didn't go overboard as some have with wastegate and main fuel scew etc but I now have a great increase in power which is enough for me. I also have a light clutch and amazing braking too! Something which I thought I'd never achieve on a Defender. I just wish they would stop interfering with test procedures in the name of this climate scam. I am going to contact my MOT station re the high revs with no load and wait and see if it passes. I may have to revert the procedure if it doesn't. No one has come back and said they did the same work and had no issues with the MOT so I still have no idea on that question. Thanks to you and everyone else who has given me their advice which is always welcome and appreciated. Thanks again.Rick's 200tdi Tuning Guide

On the wastegate thing. I blanked off the pipe from turbo to wastegate thinking I will get a bit more boost - but no difference at all - and I measure boost on the top intercooler hose. I get 1 bar at full throttle and at best there felt like the wastegate was wanting to open at the 2700 mark and that small "flat spot" has disappeared.
It could just have been my imagination as well.
Do the defender's have the ghastly egr system installed ?

They did have EGRs but removing that was the first thing I did. Awful things.
Your not worried about that being a fail (and illegal) then?
If it passes with no egr you should be ok with your adjustments I should think.
Illegal? How's that? Having an EGR is not mandatory. No one in their right mind has one fitted.
Ooops!
Oh dear!
If it was fitted by the manufacturer it is mandatory to leave it on. (See Gov.uk MOT testers manual)
Most of us who delete them, and I am one of those, get away with it either cos the tester cannot be assed to look for one, or simply can't see it cos it is hidden under the engine cover.
Evidently it passed its emissions test every time cos they don't test for that.
