means that you didnt search enough, everything will work as it should as only the faulty part is bypassed, explained here: https://www.landyzone.co.uk/land-rover/necessity-of-the-mod-svs-fix-wiring-mod-option-b-graphic-explanation.272156/

Water ingress to the sunroof ECU or corrosion in it is quite common

It does everything like all the other cheap multivehicle OBD2 scanners can do for the Td5 EMS... shows you nice but false fault codes and erratic live data, that's what they do, believe me or not

Hi. That would be the best if you want to have no issues with such things and you can install a hidden "kill switch" under the dash if you want it to be unstartable for potential thieves

Nanocom is the best for Defender no need for comparisons

Then that's the problem, might not be the ECU but a wrong fuel map.

The wastegte seems to be tighter than from factory so it should not be low on boost for that reason that became clear when you said it's from 2003.... i cant say more than i've already said about the black smoke

here's a copy from the first generation nanocom's function list:

I've seen many logs and 10*C difference between the ECT and FT is quite usual and considered normal, as about hight FT input AFAIK when it exceeds 75*C a smoke limiter map kicks in and the ECU reduces the IQ(injected quantity), the higher the rpm gets the more limited the IQ it is.

Hi. Read the fault code, i've seen such symptoms on V8s caused by the CPS or even by the MAF sensor, the code will reveal it

As i said it doesnt seem a management issue, it's overfuelled for some reason and a bit low on boost... might be from the injectors or the turbo if you are certain that there is no boost leak... is it manual or auto? also how many threads are left out from the locknut on the wastegate?

Maybe on the P38 as you can inflate all 4 of them more than normal and then it can be stiff but on the D2 being only at the rear if you inflate them more than normal the vehicle will not be horizontal and on a well calibrated D2 the ride is much better with SLS than with springs, especially if...

:vb-headbang: ^^^ that's named cognitive dissonance, unless your SLS was not working well from the beginning ... though if you want something really good i recommend THESE but never expect to have the ride quality of one with air springs despite of your biased conclusion

Even though the readings look OK unplug the MAF and drive it so for test.... is the EGR bypassed?

You might not notice it if you are not used to a well running Td5 driven with nervs. As long as you have the AAP fault code logged the ECU is on default for that specific code and one of the symptoms is "boost limited to 1 bar" so without correct AAP inputs the engine is low on power, worst if...
