Suspension setup is pretty sensitive to your suspension pressure. Changing the pressure is made a little easier with digital shock pumps. Here's a great quality digital shock pump just for the task :)

Features:

• Digital Gauge. Units can be changed between PSI, bar, kg/cm^2
• 300psi maximum pressure
• 80 second auto shut-off
• Pressure adjust button to finely tune your pressure
• Rotating hose so it doesn't take up too much space
• Replaceable coin cell battery (CR2032 3V)

Note: These are the same base shock pump as the Rockshox digital (and many other brands) shock pumps are. The differences are:

• Body colour
  
• Adapter type -  this adapter is slightly shorter and has an easy engage lever
• Branding
