Gas Mileage
So i have been surfing arowned looking at almost every thread about gas milage and i still have not go the answer i need. I have an intake, i drive with the rpms under 2500. I have changed my oil to synthetic and i have e3 sparkplugs in. I have a high flow cat and high flow glasspack. Is there anything else i can do to make it better?

ummmm.... what are you getting in city? and highway?
2wd or 4wd?
big mud tires, or close to stock?
is your speedo/odometer correct?
w/4wd about the best you'll do is 13-14 city and 16-17-18 highway at 55mph.
1-2 mpg worse with big soft mud grips.
tune up. fix plenum. stay in OD as much as possible. drive easy. go downhill as much as possible. coast a lot.

what about electric fans? also you might be able to get a bit better fuel economy if you can turn off your daytime running lights but you might not be able to legally turn them off. i think in Canada anything 91 and newer has to have daytime running light but it is not really enforced.

the plenum fix is a plate that seperates the lifter valley and the intake. it is bad to leak and let oil get into the intake which drops gas mileage alot. i fixed mine and now i get 17 avg. was 13 mpg!!
