Also do I wire everything up then set the fail safe after tuning or do I just let the wire going to the boost controller un hooked until after it is tuned?

I believe there is a "jumper" you can move in the hfs-3 controller box to disable the failsafe. So you wire it all up, but have the failsafe "turned off" while getting it all sorted out tuning. Then after you get it all dialed in, set your High/low failsafe limits in your gauge face, etc. Then you move the jumper back to its "active" mode turning it on.
