Default N54 fueling question. About to upgrade turbos... - 07-17-2019, 10:07 AM

Iím about to do a PureStage 2 turbo upgrade on a FBO 335xi running BMS methanol injection with a JB4/MHD backend. With this setup will I need to upgrade my LPFP to push to mid 500ís with just 93 and methanol? I have no intention of running e85, but didnít know if the stock fuel pump will be able to keep up with demands of the newer turbos running more power.

You shouldn't need to if you are using dual nozzles for the methanol kit.
If you plan on using e85 go with the fuel it stage 1 or stage 2.
