ya i was thinking about the distance of the test being too short but wanted to keep the test route the same.

 

Sounds like it makes little to no difference to me. On another note, I have never seen 18.anything on my DIC

 

gotta be nice to it. plus you are running 373 gears right?

 

Yeah, 3.73s, 285/70R17s, and a leveling kit. Filter, M.I.T., tonneau, and a tune are all on the way and should help a bit with the fuel economy. I should have all that done (plus a muffler swap for more character ) within a couple weeks.

 

Best number I've seen on the DIC was 16.x but that was only for a 30-minute stretch of freeway. Best average I've had on a full trip was 14.5.

 

tires gears and driving style i think are playing a part for ya! if i drive normal, not nice and not hard, i see about 16.8-17. i have to make a point for less city driving and to drive nice, 65-70 and never more than a touch on throttle, to see those 18-19 numbers.

 

Those are my playing nice, drive like a grandma, highway only miles. My normal commute and daily driving averages out to 11.8 every week. Sure I could baby it around all the time and stay mid-to-high 12s around town and maybe 15 on the long trips, but what's the fun in getting a 6.2 with 3.73s if you aren't gonna get on it once in a while? I honestly don't really try to hypermile it anymore, but 15 is about as good as it will get for a full tank. I'm pretty sure that there was a wind at my back or a downhill advantage when I was over 16mpg, because I haven't seen a number like that since. I've talked to a lot of other guys who said they noticed a big difference just after adding the taller, fatter tires, so it doesn't bother me. As long as I gain performance with no loss in fuel economy after my bolt-ons, I will be happy

 

I am leaving today on a 1600mile road trip for vacation.
I am wishing i would have kept my stock 20's instead of trading for 22's.
The most i have seen straight highway since the change is 19's.
I'll post up some good #'s and try to remember to remove the lower valance on my way home.

Not trying to hyjack thread but since i am driving that far, i figured it wouldn't hurt to try it out.

 

Good plan let us know

 

hijack approved!!!! let us know.

i will be doing a 2500 mile round trip starting on the first of july. i'll post up the results. may try taking a screw driver and lower valance.
