Well I took my new RS Sid out for its debut ride the other day. I pumped it up to the appropriate pressures but it felt too squishy during the ride. I got back home and put the fork pump on it and found that the pressures had dropped about 50% from the time I aired them up. So I aired the positive and negative chambers back up and noticed something. When I take the pump off the valve there is some air that escapes, at first I just thought this was the air left in the line. But when I put the pump back on and checked the guage I noticed that the pressure has again dropped about 50%. So my question is this:

How do I remove the fork pump and keep the air from escaping? Thanks.

If you lost 50% of your air after one ride...its not your pump. Shock pumps let out only a tiny bit of air, thats how they are made.
CHeck your valve cores, it would not hurt to replace them. I did it to my fork (also a SID), and it retains air very well. Valve cores cost me 2 dollars for a 6 pack, and 3 dollars for the tool to install/remove them..

What I am saying is that when I aired it up the first time...50% of the air leaked out when I took the pump off the fork...and I was riding with 50% less air than I thought.
