The factory wastegate fitting caps boost near 21 psi, which leaves extra fuel unburned on a modified truck. Replace it with the BD 1040310 elbow orifice to bring boost up to as much as 35 psi. It fits 1994-2002 Dodge Ram 2500 and 3500 with the 5.9L Cummins, 12 valve and 24 valve.

How it works: Replaces the brass wastegate fitting on the compressor housing, pre-set by BD, so no adjustment is needed. No core charge applies to this part.
