I have a 2008 335 its FBO (DCI,FMIC,DP, AND UPGRADED CP). Im currently running a jb4/mhd BEF. Im looking to get PI and a custom tune for my stock turbos. Which port injection option should I go with and what controller should I use. Im under the assumption I should go with jb4 controller because with the other controller options it seems that the jb4 unit is just in the way. Should I toss out my jb4 and stick with mhd or should I do the ladder? Im wondering how those with a jb4 unit have there Pi setup. Any other tips and information is very useful

stock turbos, why? just run mhd and if you needed port i would go all out and get a reflex unit

Turbos are decently healthy and im not looking to do all the labor to upgrade them just yet. Im just looking to make the most power out of them and I believe upgraded fueling is the next step. What do you personally think I should do next. Im new to the car space got the car about 2 years ago I've gotten most of the maintenance and have been slowly building it since

watch youtube, read articles, and datalog to verify its runs well. its an old platform and its all been tested. i would upgrade the lpfp and run e30-e50, then focus on mod to handle the extra speed/hp over stock (suspension and brakes)

With OEM turbo's, the most you can squeeze out of them is running full e85, roughly 500whp. That is what I did. My n54 sits at 38,xxx miles right with mostly healthy oem turbo's. You will need PI and dual LPFP's. I tried running it on just 1 walbro stage 2 fuel pump like you have but it is not enough for full e85.
