We then loaded a different map on and it ran 235 hp and 520 Nm, which is roughly where it should`ve been. We then rang DMS who claimed the car must`ve had a software update (it hadn`t, I cheked with the dealer) and arranged to send a tech out to re-do it. I took it back to the R/R 2 days later and guess what............still down on what it should`ve been.
So the 235hp map wasnt DMS's ? Why did you not stick with this one ?
