I can tell you how I set my boost up then you can form your own opinion. I have had my motor in my boat with no problems for a year now. The engine is a BBC 30 over w/alu. heads 8-71 Weiand two holley hp950's no innercooler and run pump 91 oct.gas 8 lbs. of boost @ 1800 ft. elv. engine water temp. at 180 deg. I bought a MSD knock sensor and I tuned it to the knock sensor. I also used a bore scope to confirm everything like fuel being to rich or lean and any signs of detonation. The thing works great. Just to be on the safe side I do run the fuel mixture just a little on the rich side and run the timing at 34 deg.
