MHD TO BM3 Question

[gymbmw]

Hello all,

I just recently tuned my 2018 F85 to stage 1 91 octane with MHD but it honestly feels slightly weaker compared to stock. I have flashed back and forth from stock to stage 1 and compared them, but stage 1 just feels smooth and boring compared to stock. I'm thinking about just flashing with BM3 instead since it looks like that's the main platform for the S63. My question is does anyone know if I can just flash from stage 1 MHD to BM3 Stage 1 or is there some kind of method to do this successfully? I also just ordered some catted downpipes so I will go stage two, but I'm just concerned that MHD won't give me the power gains I'm looking for so I'm thinking about giving BM3 a chance.

Please let me know if I need to elaborate more or perhaps if you have any questions I can answer.
