i have a 2008 usdm subaru wrx making around 450whp on pump 93 and plan on running 50/50 to see what more i can extract from the setup.
what suggestions do you have for my installation or tips to best take advantage of my new HFS-4?
thanks, again!

Do you have a FMIC? I assumed you do. Please make sure the two jets (yes two) is placed as far away from the throttle. 3-6" apart is perfect. This promotes better mix and allows more time for the droplet to perform inlet tract cooling.
The reduced droplets will give better cylinder distribution so you don't have to tune to the cylinder with least water whilst the others are over cooled.
The HFS-4 has three MAP sensor input definitions, absolute, 2 bar and three bar. It converts any two of the latter MAP sensors signal from "atmosphereic to boost" to 0-5V.
This is useful if you want to want to balance the meth flow between idc and boost (vacuum is nulled out).
50/50 is a good starting point.
