Then you should put a banks kit on it.
I' don't thing you'd believe anyone who doesn't get what you get.
I had a 2002 350ISC that I put the baddest banks kit available on it back in 2008 and it was very powerfull like 465HP but fuel mileage was like 7.5-8 in the combined mountain/freeway driving at best
I could get 9 but that's not a real figure to brag about because that was on long steady peddle flat freeway
