My setup:
1jz/5 speed R154 out of a jza70 supra front clip with about 100,000 miles on it.
New one piece drive line with new bolts at the dif.
walbro 255 in tank ( have not installed the 2nd inline 255 yet)
AR .70 single turbo on ebay manifold.
3" downpipe with stock O2 and wideband O2.
2.5" after-market IC with BOV (not making any sound for some weird reason)
880cc denso injectors on a top feed fuel rail with duel feed lines and middle return line.
BC 264 CAMS with adjustable gears.
AEM EMS version 2 with base 1jz map.
Running ~12 PSI

So after my swap was finished I babied my car when I drove it just to make sure everything was working ok. Then I took the car over to my buddy's and he wanted to drive it, so I let him and he drove the car hard. That is when we found that under boost the power steering stops working. There is not noise at all, its like someone just hit the light switch and turned it off. If you drive the car nice for about 10 minutes it comes back and works great until you boost again.

I'm lost as to what to do!!!

Any help would be great.
