Will this feel stronger than a tmc box?

Thanks for the info. Kinda strange the F series has been opened up via OBD but not the late E series
The reason is that the exploit for unlocking the DME in an F series is not the same for late N55 E series cars.

It will be better than any piggyback as it isn't trying to trick the DME into doing something it shouldn't.

Stronger is a subjective thing - you would need to dyno then drive each tune back to back to get meaningful results. I'd rather have a proper remap than a piggyback. you can stack the MHD and JB4 if you want to run a Meth map.

Is MHD reversible? i.e. can it be detected?

Yes, it is reversible in the sense that you can flash back to stock...however that does not mean that tampering with the ECU map would be rendered invisible after reverting back. It's all about who is looking and how hard they want to look. Anyone who says their tune (or rather the process that they use to tune) is "untraceable" is lying to you.
