Well jeez, I didn't want to say anything about having a boost controller installed, but now that you mention it, it is a fairly simple job. I've helped with a profec-b spec ii install on an sr, it was simple as pie. We didn't even get the power lines with it at the time and I had to fabricate a power cord out of speaker cable. Some heatshrink on the stripped ends to make a nice temporary plug was all it takes to git'r'dun .

As far as manual boost controllers go, my personal favorite is my homemade 10 dollar ball-and-spring mbc. It was holding 16 psi just fine with 1 psi spike, can't beat that for 10 bucks. Didn't work so well on the sr we tried it on, though . Every other turbo car- works great, sr car- no good. How is your mbc working?
