If you followed the book to the letter then should be ok. I have this one and it is perfect. You may have to turn your gain down if it is spiking uncontrollably. Try 10 on the gain and set gain should be 4lbs below the boost you have it set at. If working on 10lbs boost then "boost set" should be at the percentage it takes to reach that boost with gain at 10 and set gain at zero. Once you achieve the 10lbs boost slowly turn up the "set gain till spiking occurs then turn it down 2lbs. Then turn up your "gain" till spiking occurs then turn that down two clicks, that should do it. Then get a tune for God's sake as boost will be coming on much lower in the rev range. After tune fine tune one or two clicks higher or lower.

all ok now, had to use the solonid like a internal gate should be and hook it to the bottom of gate and just a normal pressure to the top and now works fine. thanx anyways
