First up, I thought these had stock spec of 550Nm and Stu estimated extra + or - 112Nm with Flash Tune? Unless I wasn't listening corectly. So to give the benefit of the doubt, that is why I would like to get tested so that I would know for sure but getting it tested would only be so that it was factual and on a piece of paper.
The car does everything I need and most of that is pulling my van and hauling equipment around for my day job. If it is 600Nm + or - it doesn't really matter too much to me as I am really happy with these Commanders and the motor they have.
I just hope that it lasts and lasts for a long time like my old Prado did (480,000 kms - Petrol - No work to Motor) then sold it
As I do around or over 1,000kms per week travelling with it.....
