So, if i get the pully conversion and eliminate the smog pump altogether it wont make the ECM throw codes or the check engine light to come on? Thanks DW

just get a shorter belt. cleaner engine bay, less crap on there and it wont make the check engine light come on.

i have everything disconnected from mine but its still on there. i have no check engine lights, only thing it does is show a couple codes when i run them.
