Very close to booking my E60 M5 in for re-map/chip has anyone had it done and is it worth the money, and does it make it any quicker etc? Really could do with some advice on this they tell me its makes the car quicker but im not that sure!
Could have told you David, was about to do a back to back standard M5 vs DMS one... but the gearbox failed on one of them before it even got to the unit
I wouldnt have it remapped unless you were going for headers ect. The EVO sport power pulleys seem to make a good difference to response,mabe try those they reckon 20bhp.
