A Powerchip tuned 2006 E60 M5 takes on an Evolve tuned 2007 E60 M5 - Result is not pretty
These are the videos we like to see, comparing the same cars with different mods. In this case the camera car has an Evolve Stage I ECU tune, RPI scoops, RPI pulley, RPI block off plates, and an Eisenmann muffler. The other M5 (2006) is running a Powerchip tune which used to be one of the best tunes for these cars but Powerchip is pretty much on life support (if not dead entirely) and is living off their past name and tunes which have not evolved as the Evolve tune has (pun intended).
In addition to the Powerchip tune the 2006 M5 has a full BBI exhaust, RPI scoops, and RPI block off plates. It is surprising the Evolve car pulls this strongly when it does not even have a full exhaust.
Both M5's are S6 with DSC off and P500S mode. The AC is off in both cars and each has 1 passenger. Camera car has slightly more fuel. Enjoy the video below.
