With a Puma you should be running a max of about 600 degree's pre turbo...
The biggest problem is that most tuners have no idea about EGT - and use the old method of adjusting PW without understanding it's affects especially on a modern common rail diesel as per a 2.4 Tdci... mainly as they have no idea on how the calibration works. Running the temperatures mentioned you will get turbo failure... at the least. I would imagine you are also getting excessive black smoke.... and have low MPG?

The strange thing is that i don't get much black smoke,especialy compared to my disco td5 when i was trying some stage 2 maps and generally the tdci and vnt combo(and 6 speed gearbox) smokes a lot less even tuned.
Many people suggest that when you see egt's rising you downshift in order not to labour the engine etc. In my case,i'm not labouring the engine when cruising with 6th and 2600rpm,even if i dare to downshift to 5th revs go up to almost 3500 so only way is to reduce speed. I get smoke when revs are over 2500 and "push" it then you see the egt meter running faster than a stop watch!! So that's i conclude that the specific tune gets quite "hot" after 2500 rpm. Anyway as i already wrote i drive accordincly,hope previous owner also 
You say 600 PRE turbo and tuned? Do you happen to know stock pumas egt's? Numbers anyone else please? Apart from observing the egt's,i'm generaly satisfied-compared to td5 that is! PS AFAIK the specific puma was originaly tuned by you back in 2008 for a Lybia expedition, one of the first pumas tuned,you came yourself to Greece to prepare it but a year later the setup of the whole def "changed" so your tune was "lost". I'm still trying to collect the full history of my(now) puma. |

With a tuned Puma you shouldn't get any smoke...
This was before it got up to the 200bhp level, but even now it doesn't smoke. Done properly even tuned you should be able to sit at max load without worrying about the EGT. Arhh.. you own the Keswick Green 110 (what made me like the colour in the first place) that features on all the safety devices adverts!

I wish remote remapping-nanocom style- was possible...

Think I need another trip to Athens.... been a while.
Max EGT under full load on a standard Defender should be 475 - 525 degrees.... over 600 degrees and it's getting way to hot.

I have a BAS remap V2 and a Madman unit. With the remap, I have noticed that when I park the landy at home or work, the EGT is much lower, sometimes by about 30C or so. Usually by the time I have idled my way in 2nd gear from the main gate to my parking bay at home (100m), the EGT is sitting at: OEM map: 180-190C BAS remap: 150C-160C Also, when cruising, the EGTs are lower with the remap. And of course, when accelerating hard, the EGTs can climb very quickly, but you have to learn how to stay in the optimal gear and rev range 
My EGT alarm is set at 650C, but I very rarely hit that. When I do it's usually because I didn't gear down from 6th to 5th on long uphills. If you are in a warm climate, you will also benefit greatly from an upgraded intercooler, the OEM one is useless for anywhere else other than the UK --

Post Turbo then...
Pre turbo is really the better place to measure from - ideally where the collector is just before the turbo to take an average of the whole manifold. EGT under full load is the more important thing to look at... Any calibration shouldn't rely on the driver to limit EGT.... you should be able to drive flat out in any gear and not worry about causing any damage.

I have my EGT probe fitted pre-turbo. I also have an Allisport intercooler, but no remap.
At cruising speeds (110-120kmh) my readings are in the 550deg range on a level road, but they have climbed to 720 on a long hill in high ambient temps on one occasion, although it's usually around 650 on that specific hill. I have found that backing off even 5kmh makes a big difference to my EGT readings. All readings are driving in 6th gear. |

I recently installed an EGT probe, a pic of the sensor:
My 2.4 engine is BAS remapped with Chiptech intercooler and high flow 100 cells cat on the exhaust. Until now, I mainly drove the car with external temperature between 0°C and +5°C, so fairly cold. Average EGT temp when driving in 6th gear at +- 110 km/h on flat road is around +350°C Maximum temperature actually reached is around +500 when pushing fairly hard on the throttle (5th gear at 3000 rpm on a sloped road) I see that my EGT temp are lower than most reported on this thread. Do you believe it's due to the post-turbo sensor position or the intercooler+high flow exhaust ? How much the ambient air temperature affect the EGT temps ? |

I know people have different ways of testing and also have sometimes different quality equipment available for testing as well as different conditions testing in etc etc blah blah so results may vary from one to another for those reasons.
Ingoring that bit here is what I found. When we did the Allisport Defender many moons ago we tested temps in various places on the allisport Defender standard and tuned with different setups that we had available at the time. A few pics in gallery https://www.defender2.net/gallery/thumbnails.php?album=440 We tested intercooler temps and boost pressure.
We tested the EGT in turbo collector its self as well as after turbine.
As standard depending on the driving style done, outside air temp, beleive it or not fuel type used and more I can barily rememeber and we could make an averaged out EGT of anywhere between 500-520 taking it semi easy and then right up to 740-760 when worked hard and some times occasional spikes as high as 780+ giving it stick for a long time sat hard on the 132kmh speed limiter as a standard untuned but intercooled car! I did this several times back anf forth to Gloucester, and I do agree with Ian that the longer the time the engine spends at super high EGT the more likely it is to become a problem. Prevention is better than the cure for sure so if it can be kept low or lower the better overall. These are just my own findings with the tools I have used on the cars ive used them on, others people may see slightly different results on different cars with different set ups etc etc at this thread shows.
