Will running a high octane fuel help with passing smog? and what about smog addative, what exactly will that do? I gotta go smog my 4 cyl mustang before I convert it so I just wanna find out what will help out, I already got new cats and cleaned the EGR out.

the gas wont help, dont know about that additive stuff. I say just get it tested and go from there, you might be doing a bunch of work for nothing
