Mhd stage 2+ e50 on n55/135 without extra injectors?

[StevieJ2]

Have an n55e with brand new hpfp and a bmp stage 2.5 V2 lpfp, with fbo, stock turbo. Would this setup be ok to run e50 with? Currently I can run E30 without issue as long as I use Sunoco 100 octane as the fuel, my car generally doesn't seem to like the 91 octane stuff here in NV. Wasn't sure if bumping it up to e50 would require pi or not.

Anyone do this without pi and have no issues?

I ran E30 with the OTS MHD stage 2+ tune and 91OCT with no issues. I'm FBO with stock turbo N55 just like you.

I just upgraded lpfp recently to Boost Concepts and have gone thru 1 full tank of E50 with no issues. I have not touched the hpfp or pi

what year n55 you have? i have 13 but i can't use E50 tune. won't let me flash it.

Stock HPFP? If so it likely won't work. You'll need to upgrade to the Dorch or Spool HPFP.

2011, I haven't tried to flash it yet, will give that a shot first to make sure it even goes through.
