Seems to be a great mod at a great price
And backed up by dyno runs.
Interesting to see that as more and more products come out for the M5 they are also backed up with dyno charts of before and after runs. Remus also had a dyno chart, just as Akrapovic, Supersprint and Manhart has provided (to name a few). Now we also have Eurocharged with a dyno result.
And no one with strange curves or unnatural behaviour. They also seem to be very consistent between the different cars that has been dynoed.
Either everyone must have been dynoed exactly according to the criterias pointed out by Coldlist or the M5 isn't as sensitive to having the hood closed and wind speed etc.
As we get more and more dyno runs that seems to be consistent (both US and European runs) I find it harder to believe that the M5 is allmost impossible to dyno correctly. I'm sure that you definitely need to take care of factors such as heat soak, temperature etc. But do all of these dyno rooms have variable wind speed facilities etc that apparently they need to have to be able to dyno the M5?
But maybe I'm missing something here?
