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.
