Re: getting the most mpg
Chip/programmer, intake and exhaust will help. BUT then you really have to control the foot, because the new found power is too fun. Ideally on the highway, stay under 2k rpm. That is the "Sweet spot" for cruising. I have gotten up to 23 on my early 99 at about 1700 rpm for several hundred miles with cruise set. On my early 99 1700 was about 62mph. I can't do that. On my 03 its slower yet, since I have 4.10 gears. Really, you and the jackrabbit starts,late stops, ect... have the single most impact on your economy. (Not saying you do that, but you get the point I hope) There is no "MAGIC" thing out there that will let you drive like you normally do, and get huge increases in mileage. (the economy is there if you want it,,,, by changing your driving style)
