| 870 0482 code, low boost 2005 cm870 cpl 8520(demandated via running rough 475hp tune) had 1 occurance, and inactive now code 0482 for low fuel pressure. On insite it showed 249.7 psi @ idle, and 262.3 psi @ about 1400 rpms. also, its never really been able to boost over 32 psi. I thought these things will go 38-40 psi? truck always seams sluggish and feels like you gotta drive the hell out of it to get it to move. Is this normal to have to floor board these things all day? Ive heard the 870 is one of the best ones to have as far as ISX goes, im not impressed with mine. Ive also looked all over the web for info regarding HP/TQ ratings for different CM870 CPL #'s and have had no luck. What are the ratings for 8518,8519, & 8520? | |||
