Can a good cold air intake and bypassing my egr help with fuel mileage? Any other mods to help as well?
and if i just take it easy my info thing will get up around 21mpg dont know how acurate those things are though!!!!
A good tune will do the most for your economy - intake and exhaust will help.
If you can discipline yourself enough to keep your foot out of a big tune your mileage will greatly improve, the added timing really makes a difference.
