thanks for this info

i Dont understand why i need to upgrade the single walbro 450 fuel pump because I make well over 600whp on full e85 with a single walbro 450 in my honda s2000. I'm only making 504whp with my 335i amd it only runs 50%e85.

but yeah i been thinking about getting port injection.

Do you think there is more power to be made with my 335i without upgrading my single walbro 450 and with out getting port injection.
