The jets are .5mm green banded. I run a 6th right before the air temp sensor to trick the ecu into adding more timing. My pump is either 150 or 200 psi. Can't remember. It's high enough I don't worry about pressure drop on high boost.
All controlled by an aquamist fast acting valve on a spare injector channel that is enabled by a Hobbs pressure switch around 15psi
I also have an AEM fail safe system that monitors flow I plan on having it disable high boost if flow falls outside the normal map.
I have a lot invested in this system so it would have been silly not to run it! Only a few extra evenings so far to get it installed completely stealth mode.
In regards to the fuel, I run one of these gauges (in addition to 5 other gauges) in my S4. Its a nice unit and stores your max, so at any point you can hit a button to see your max from the last pull you did, or hold the button down and reset. Kind of a nice feature, so if you're at 30 PSI you can focus on the road.
http://www.demon-tweeks.co.uk/motorsport/gauges-auxiliary/spa-design-turbo-boost-fuel-pressure-dual-gaugeThe AEM failsafe is a must! The only issue I have ever had with it is if the pump flow is somewhere in between low and high. I have seen a scenarios before when it was clogged where it was at about 200 ml/min and so it was enough to not trigger the failsafe but less flow than I want.
It's really a cool system when set up right!

I can't wait to get the Failsafe setup in dad's car. Definitely worth it IMO

Randomly came across these. Kinda like finding $50 in your pocket. I was just starting to think about making some shrouds and how to cleanly fasten them all together.

Yes, apparently I bought a value pack sometime ago. I should clean the garage more often!
Pic for progress.

Spent all day wiring things up. No fire yet, but all wires are mapped out and ready on the VEMS side.

maybe etch the numbers into those connectors as well as the magic marker? I have the cheap harbor freight electric engraver, works great.

Etching is so permanent. What happens when I have to swap in a hyper drive?
