    Engine Type = OHV5.7L HO ?

    When comparing a couple of C5 tunes I noticed that in the Engine General Section under Engine Type one tune had OHV5.7L while the other tune had OHV5.7L HO is there any difference in the way the tunes perform or is this strictly cosmetic ?

    Thanks >>>>> INTHERED

    Other than the 5.7 HO is the LS6 engine and the 5.7 is the LS1. That is unless someone changed the designator....

    I realize this is old, but its 6 years old and I noticed the same thing in my 0411 PCM in my S10.(because I swapped the 4.3 to 5.7)

    Any new updated info to this?
