With the release of mhd+ for n54, what is the best way to run e40+ with the new options. Right now the car is stock fueling wise but I'd like to build an ethanol capable platform without using outdated gear. Stock turbos for now but I want to get fueling right and eventually likely to go big single or pure stage 2. Still on the fence.

if you want big power later with the awesome new tech out, I would just worry about buying/hoarding everything and youre gonna want relfex

You want to run E40? Easy...install a Walbro 450 LPFP, and run a tune that's set up for E40. That's all you need. Your HPFP should be able to support 550-575 HP on E40. The MHD V5 Stage 2+ E40 tune is awesome on stock turbos!

Now if you want to run straight e85, then you will need to step up to a full port injection setup, and probably install a second LPFP. Honestly, going to port injection is a waste unless you have a big set of twins or a big single turbo. You are talking 600+hp.
