What is more important, is that any readings it gives, are consistent. And you seem to say that they are consistent.


IMO the numbers are totally irrelevant, as there will always be disputes. Gains seen before and after tuning are important, as is performance on the track.
If you want to compare numbers, only compare with other vehicles or engines used on that exact same dyno. Not others.
