Funny that you should mention the PG2 because I just installed it on my 350. I'm very impressed with it. I'm getting 21.5 FPE, which is more than I thought I would. The shot cycle seems more like a gas piston than a springer. It still has some kick to it, but less than it used to. What kind of FPE are you getting with your Feuerkraft now? And by the way, what is that white cream lubricant that comes with the kit? Strange stuff, but it seems to work well.
