MHD tune?

[Tyler Andrews]

Hello I just recently bought an f10 m5 coming from a big turbo b58 4 series. My car came with catless downpipes a bpm stage 1 tune, and ssp r spec clutches for dct. Im considering getting a MHD super license (all the tunes stg 1-3 all oct) for ease of use, I do not know neither does previous owner how to change the tune. I have the MHD adapter and am familiar with the system. Just checking to see if I was downgrading my tune or if MHD is bad for this platform because there isn’t much info on their tunes online for s63. Also can I just flash over it or would I need to flash stock first? Please inform me. Thx.

You can flash it right over. MHD tunes aren’t bad. Custom is always nice. Most seem to go with BM3 ots. If you custom tune with MHD I would just have Fabian from Pure Boost dial it in and if you decide to custom tune with BM3 I would have Halim from HCP dial it in. Those are the only 2 tuners I would go with with my M5.

hows it going im new here. been an f10 m5 owner for almost 3 years and finally getting on the forums...ive always just browsed. i have a 13 m5 dct just hit 107k miles i have the mhd super license currently running stage 2 e30, eventuri drop in filters, catless vrsf downpipes, cts charge pipes, vrsf intercoolers, resonator delete and i havent had any problems. i like the tune as its ots but i am curious to get it dyno tuned. i highly reccomend it because again i just flash and go. huge difference from stock
