A) TU Fuel pump
B) MHD FlexFuel Analyzer Kit
Install , change Flash to Flex Fuel with the slots 91/93/95/2+ 95
Is it that easy?

What are your goals for running flex fuel? TU pump is needed if you want to run anything over E25/E30 blend on the Gen 1 B58. I've been running 3 gallons of E85 in my tank (E23 blend) and have had some fuel rail pressure drops and trims getting high with both the JB4 tune I had and now with MHD stage 2 93 octane.
I recommend being able to data log and send to experts for review. Jump to different maps and check out the metrics.
But getting the TU pump installed will remove a lot of the worry and hassle with getting the Gen 1 B58 dialed in on stage 2 and beyond maps. The flex fuel kit would be super convenient for seeing your E-reading. I've just been doing the math every fill up.
