PIMPs don't suffer from FSDO, that was one of the big design differences in the PUNCH2 and using the Timmy noid.
I have the NDZ ram in one of my PIMPs and it gets worse efficiency than the stock PUNCH2. Put them both side to side and you'll see the double oring portion of the PUNCH2 holds far less air than the improved channels on the Slick shot. Also the back macro fitting in the PIMP (as oppossed to the fron on an IMP)puts air straight into the PUNCH2 while in the NDZ it has to travel Forward to the air channel and back to the rear to enter making 2 90* turns. The NDZ ram is very tight where the air inlet is on the PIMP. Air must squeeze through the sides fo the ram to get up front where the IMP inlet would be and the actual air channel begins. Also the PUNCH 2 has air inlets all around the circumfrance. Position doesn't matter. The NDZ has only 2 inlets, yet another 90* turn if it's not lined up right when screwed all the way in. Finally it's not adjustable. The slick shot ram piston is smaller (Thinner) than the PUNCH2, yet again more air needed. The only advantage of the slick shot is the weight of the piston and hammer. Lower mass = less LPR needed to move it at high ROF. Draw back of less mass is more LPR or Dwell needed to actuate the valve. The net loss was I had to run higher dwell and LPR to get it to activate the valve properly 100% of the time. Bottom line , I am still playing with settings, but I get about 150 less shots with the NDZ ram.
Finally, the PUNCH2 is adjustable. not a big deal untill you use small bore paint and the ball rolls back off the eye.
Notice the pics.
Bottom line, I tried it on the PIMP to see if it was an improvement over the PUNCH2..It was not.
