Talking N55 Pure Stage 1 Upgrade! Everything Needed and a DIY

It's official! Placed some orders just a few moments ago, I'm going to outline the process from start to finish for going to a healthy and reliable Pure Stage 1 setup on an N55 car, specifically a late model that needs a DME unlock since many people haven't documented this.

Goal: A healthy and reliable 400+ whp car with multiple maps available, primarily one for 93 octane and one for an e85 mix. I want the car to remain as bulletproof as possible so certain things outlined below are not 100% required, but certainly can't hurt. Eventually I might end up going to the PS2, and with these mods I'll be ready for it.

Supporting Mods:

Turbo Mods:
All of the above supporting mods have either already been installed or are on their way. In this DIY I will include instructions for the 7" Intercooler, Stage 2 LPFP, the Turbo itself, and the DV+ installation.

I'll be completing the DIY's as parts arrive over the next couple of weeks, and then documenting the tuning process after everything is installed.

Parts have started to arrive!!
