MHD Tuning

MHD Flasher is the first Android handheld application to bring ECU tuning and monitoring to the BMW N54, N55, S55, B58 and N13 engine. The MHD Flasher reveals the immense margin of power BMW left on the table with the N54, N55, S55, B58 and N13 motor, while still retaining the sophistication of the original engine management program.

My first dealing with Southern BM was a pleasant one. I had some springs and shocks installed and Sean was a delight to deal with. Knowledgeable, helpful and offered solutions when not everything went to plan. I would happily recommend them.

One of (if not THE most) professional outfits I’ve dealt with - in the auto industry or otherwise. Needless to say, all work was carried out as promised and to an impeccable standard. Thank you Sean and team - you’ve renewed my faith in the auto business!

Great experience dealing with the team at SouthernBM. Sean in particular was fantastic with his knowledge, timely responses and ultimately work performed.

I have used many mechanics over the years for the many different types of vehicles in our company fleet and southern BM is one of the very few workshops I can highly recommend. Andrew and his team are also really passionate about their work and it shows.
