@DXX @DaveD @JOG I think this is fair comment from a new member of the forum. His question was targeted specifically at those who might have long term experience of a Pendle map on the 102 Euro 6, which seemed a reasonable request to understand real world experiences and in some way mitigate the potential risk. It's clear from many of the posts from some of you that you're experienced engineers and a lot of what you say carries real value, but a new member making an honest request for some real world feedback didn't need that reply.
The first line is relevant advice, but I don't think it needed the sarcastic (maybe tongue in cheek, but I don't think so) reply about Rolls Royce engines on passenger aircraft. There really is no relevance to the question that was being asked and the consequences of one failing and possibly (note that I've said possibly) resulting in the death of hundreds of passengers really doesn't reflect the consequences of a damaged gearbox/clutch/turbo or whichever other potentially delicate part may be affected by the remap.
For what it's worth
@Langers , get in touch with Pendle if you can, keep asking for real world experiences of his maps and you might get some answers that help you decide one way or the other. If you go to the right place for a Pendle map, or Pendle HQ and use the rolling road, the map will at least be tailored to your vehicle, rather than a generic map downloaded from the company server like a Revo one would be.
I should add that I'm not affiliated with either Revo or Pendle, but a bespoke map, albeit one probably derived from base generic settings, must be a better option than a generic one. From what I've read/discussed/researched, Pendle can be a tricky individual to deal with at times, but it does seem he takes a sensible approach to his remapping.
Stick with this forum, it's a great place to pick up friendly advice and you'll learn an awful lot here.
