Indeed a Porsche and that's the thing:

MSD I trust completely but from what I can gather DMS are highly regarded in the Porsche world as well...

MSD claim 35 horses extra and 80 Nm, DMS claim 76 horses and ?? Nm...

So you'd be tempted to call bullshit on the DMS numbers BUT Porsche used to offer and upgraded wich also gave 76 horses extra and DMS are not know to be cowboys...

Pricedifference is also HUGE:

MSD around 350 I think and DMS around 1200 but they send you a handheld whatever to upload the maps...
