Dave (and all): 

I've been following this thread with great interest and I admire your
knowledge on this subject, but I must admit it's a little beyond me. I
have a simple question though.

Does changing the spring to a stiffer one (or tightening it down) change
the boost amount or does it just change how fast pressure is built?

You may have seen the 1.8 bar spring being offered by Europrice - what
exactly is the benefit? Any downsides?

Thanks,
