stock Ls400 fuel pump capabilities
just curious... anyone know the boost ceiling? Im running 7psi w/ RRFMU and didnt want to upgrade the pump unless necessary. I dont get any choppiness at high rpm and it seems to be doing its job... but dont know. its funny how replacing an old fuel filter can do wonders on performance... just did mine and now quicker response. Any help appreciated
