Help with KA-T setup. Turboing the car soon.

[KAs14slider]

Hi guys, I am about to do my turbo setup and I had a few questions:
Does it matter where I mount my BOV: cold or hot side? It's a blitz DD.
Is there anyone out there with a similar setup that could tell me some safe SAFC II settings so I can drive the car safely before getting it tuned? Basically I would want to know the settings that I would need to make it run rich enough so there is no danger of it leaning out on me. I have the sr injectors in there right now on a stock KA and I just did -27% accross the rpm range at both low and high throttle and the car runs fine.
Are ebay boost controllers ok or should I get brand name? I was thinking of maybe getting one but I'm not sure, I was hoping for around 250hp, is this achievable with this setup at stock boost?
And I also heard you can basically do a home made boost controller, any info on this?
Any help is greatly appreciated, especially any incite into SAFC II settings.

Thanks, Alex.

My setup:

-s14 t28 at stock boost
-Ebay Godspeed FMIC
-Taurus e-fan
-Megan 2.5" catback
-ebay manifold and downpipe
-Walbro 255 pump
-SAFC II
-SR 370cc's
-stock s14 MAF
