just looking........

I have a SO (I live in CA) and a friend of mine has a HO (he lives in OR) I asked him what the differance was and he told me that one of the differances was that they had bumped the fuel pressure up from 16,000psi (SO) to 25,000psi in the HO. Is this true? and if it is, then would a EZ in an SO bring the pressure up to the 25,000 ? All my searches about the EZ talk about higher fuel rail pressure being a risk. but if CD is already doing it in the HO, what would it hurt on the SO. Am I over thinking this... ... ..... ?



any info appreicated :D
 
No, the HO has one point higher compression ratio than the SO (17:1 vs. 16:1), and the ECM is programed different. This is in 98. 5-02 engines. For '03 HPCR engines the answer is here cummins.com
