Hi
I have recently sold my 2014 E63 AMG tuned 720bhp, Was originally looking at changing to RS7 but I've ended up buying a f10 M5 in individual grey apparently 5 in the uk in this colour, Just a few questions
JB4 what actually is this? and isit necessary to run this to able to tune the car?
Is the f10 faster when roll racing equally tuned Audi RS7/RS6? I'm expecting it to be faster then my previous E63
Is the BMS intake any good? I want an open intake for noise
Also I'm probably going to take the car to evolve, but what do people think of wrench studios? I'm hearing some good things
Thanks
