The reason the car was done on a second dyno is for all our evolve tunes have been on a dyno jet. Since the first dyno was on a mustang we needed to confirm the results on a different dyno. The results we needed to compare to a dyno where we know we've gotten contestant results with evolve tunes.
Simply strapping down a car differently can affect the numbers and since the shop with the mustang is not one we use, that is another variable we have to look at.
Evolve has been tuning diesel cars in Europe since 2007. Its not an issue if they can tune the 335d but to make sure there is not anything special needed vs the European cars to the US. Which we already found out by Bench flashing the first DME that the hardware is set up a little differently.
