Antonio, I adjusted my PCP qb78 last week, I left the valve alone, drilled out the bolt, no probe and followed the rest of CharlieDaTunas advice. I can now get over 38 fpe, but have turned it down to 24 to save on air. It worked for me :)

Antonio,
I have emailed you 2 pictures, not good but should give you the idea. I woauld agree about the bomb but it is a propper conversion with a new pressure chamber so I feel safe enough. I was told to fill it to 170 bar but it works better at 150 :-)
