putting a Low Pressure Chamber (correctly called an Air Reservoir, "Low Pressure Chamber" is very misleading) on your spyder does not make it operate at lower pressures or more efficient unless you are using a low pressure valve (does not include a "Turbo Valve"), and a regulator. the only thing it does is increase the volume of the air chamber...and a small air chamber at 800psi is the same as a larger chamber at 800psi.
if you want to go LP on your spyder you would need:
-Low Pressure Valve (i.e. AKA Tornado Valve)
-Regulator (any brand)
Low pressure will work with either CO2 or Nitrogen, but Nitrogen runs no risk of hurting the LP Valve like CO2 could.
