Quick update...so after I re-read the instructions turns out that early LB7's have a plug behind the first plug on the rail. So I pulled her all apart, removed that plug and drilled her out 
. Thats my bad....Put her all together and what do ya know, I had my log going and I saw that my rail was at 25xxx at idle. So I checked power to the box again that was good. Changed regulators at the second cp3 and same thing. Box must be bad correct? So I removed the serp belt just so I could move the truck and then it started smoking horrible white smoke. Checked balance rates just for the hell of it and now I have two that are maxxed out 15mm3. So I think I gernaded 2 injectors too!
