So im thinking of ordering stage 1 cams to go along with my new header and dual exaust (2.25 piping). But does this hurt MPG. IF it does does anyone know how much. I can deal with maybe liek 1 mpg loss, but if it ends up being liek 5 no way im out lol So if anyone has these let me know, did you actually see an increase in performnace, loss of mpg or even dare i say gain? Also probaly going to get an intake as well, but doubt it, and an underdrive pully, so with all this MPG increase, same, or loss, thanks!

my guess is that it could....but u'll notice less gas milage with port and polish
