I couldn't find the search bar on this forum anymore so I hope this isnt a repost, which I'm betting it is. I am about to down size my pulley from stock to, I think I want a 3.4. I have a 195 tstat and an intake. I would get colder plugs and probably eventually a ubend delete and a pmc from zz. After that I was wondering what range of mpg to expect for average driving.
