I am not really entitled to answer, as I don't have a CPR box, but I have gone from H2W to a DNA filter + sommers door mods, which flows similarly with the CPR at least for small throttle openings. What I found, is that to eliminate popping on deceleration I had to turn the fuel screws 3 turns out which is more or less the limit of their adjustment range on the rich side and still pops a tad, but goes much better than H2W. I only touched the fuel screws and the mains going from H2W to DNA. So, I would suggest if anything to fatten up the jetting in this area if you change to a free-er flowing setup, but that might not be necessary.
