F12 tuning questions?

[thurstonhowelltha3rd]

Hello everyone. I am interested in buying a 2014 M6 and coming from the n54 world I have a few question about possible hp gains.

1. Can the f13 m6 run e85 with a tune? If so, What concentration?

2. Has the jb4 been known to be problematic on this platform?

3. Is 650whp a possibility? If so, what is needed?

Thanks in advance for all responses.

At this point with how much the user group of BM3 has grown recently, I’d say Bootmod3 > JB4. Although if you want a custom tune I’d highly suggest DME Tuning as that’s what I’ve got on mine with no complaints. 650whp is easily achievable although clutches usually start slipping at any more power than that - traction can also be an issue depending on your tires. You’d need to be catless in order to get the most gains out of your M6. I’m not expert but hope I was able to help you out a little
