The E90M3 has a fuel pump module regulating voltage to the pump to adjust flow. I think the module will conflict with the voltage booster. Look into what Drew did on his VT700 kit — others with big power have converted as well. I cannot recall the details but you can search. I think they convert to a conventional fuel system.
But beware as others have cautioned that around the same time you need more fuel if running 93 pump you also need stronger rods and lower compression. If running less efficient (but higher octane) E85, the point at which you deliver less fuel is reached earlier.

Yeah that makes sense. Currently im at the point to where i will go back to 93. I dont see it running out of fuel with running just 93. of course i will see a significant drop in power but it will be worth it to have a working kit till i can figure out this fuel system. I like running e85 because it is a lot harder to detonate e85 vs regular gas
