Bosshog read here-Regarding the PowerMax for 1998 1/2 - 2002 Dodge Cummins 24 valve engines:
The PMCE (Competition) adds 180 HP and 450 lb-ft Torque (on level 9) for the standard engine. The HO (High Output) engine (2001-2002) already has 245 HP and the PMCE (Competition) does not make as much of a difference and adds 80HP and 310 lb-ft of Torque.
The PM3 starts cutting back at 3000 RPM. The PMCE (Competition) starts cutting back at 4500 RPM.
BS the comp version fuels to 4500rpm. I ran both TST's and ran an edge comp and drag comp and the comp and tst fueled to 3200-3300 and the tst comp and drag comp fueled to around 3400-3500.
