N55: XDi-35 HPFP. Base model or "for MHD"?

Hi all,

after my last thread talking about some misfires under load, I took a closer look at some new logs and it looks like my fp_h crashes well under 10psi when misfires occur, so I figured its time for a new hpfp.

Luckily, the black friday sale just started at TTFS and I copped an XDi-35 for $300 off! However I have one question that I'm still confused about.

TTFS offers the XDi-35 in three ways: the "base" version (normally $1,995) and two additional versions "for MHD" and "for BM3" (each at $2,295 iirc). However, the "base" version makes you select how you plan on flashing the pump params, and includes options for BM3 and MHD anyways. So what the heck is the difference?? I purchased the "base" version and I plan on flashing it with MHD (now that they have a tick box for the XDi fuel pump on all of their maps) so I'm really hoping I didn't get the wrong product.

Right now I run a JB4 with a BMS BEF you can get from their MHD BEF thread, and when flashing BEFs MHD still gives you the option to tune for the XDi if you're running one, so that should work fine right?

Thanks!
