yes, from experience, an HO pump will not work on a SO engine with an SO ECM, dont try it, waste of money. it has to do with the programing and internal setup of the HO pump which cannot be altered, and you cant get a flash to turn a SO ECM into an HO, only way itd work is if you try swaping the ECM to an HO ECM which will help, ive got one brand new for an 01-02 HO 24 valve, if you decide to go with the HO pump, pm me if interested.
