I have a 2002 supercrew and I love it. I am just wondering when
I will start getting beter than 13 mpg. I have only 4200 miles
on it. I have already replaced the stock air filter with a K&N,
and changed the stock exhaust out with a gibson 3" cat-back,and I
still only get 13 mpg. My next thing is to chip it but I am not sure
of how I feel on this. Does anyone have any experiance? By the way the exhaust and filter do help. It seems a lot more responsive.
