BEST PERFORMANCE MOD.....

[cowboy02]

What do you feel was the best modification you made to your truck/suv that gave you the best increase in Fuel Economy?

I got a lighter pair of shoes so I wouldn't press so hard on the gas pedal...

 

Actually, I would say that my K&N FIPK has increased my mileage a good 3mpg on the highway (about 21 mpg on highway now) but some people say it hurts their mileage.  It different on every truck!

Ditto on that! It's amazing how much better my new truck's 6.8L mpg is when you keep the rpms around 2000.  When I had my Silverado 5.3L I could vary the mileage as much as 2 to 3 mpg depending on how hard I ran it.

Install an uncooked egg between the gas pedal and the floorboard.

 

Seriously, I have yet to come across a mod that will pay for itself with mileage improvements in less than a few years.

That about say's it all. I have noticed that if I just watch how I drive and keep it on the ole' double nickle I get the best mpg. Oh and that is the  speed limit on my twenty mile commute anyway.

 

It might be just me but I also feel changing everything out to full synthetic might have helped. Heck it has to have freed up something, at least I would hope. But then it can be just my big head telling me there is a difference.

Definately the uncooked egg mod is the way to go if you want better gas mileage.

all my stuff otogether got my city MPG up to where the highway used to be, I think

I drive my '03 65 miles a day round trip, 98% highway miles. This might sound stupid, but my mileage is much better at 68 mph, than at 70. That 2 mph makes a discernable difference in my mileage. Next is to upgrade to K&N, then go with a tonno.

I like the egg Idea, I guess I just need to make sure I have a good floor liner in case I need to do a little racing    

 

I think that a K&N Filter kit is a good Idea however if you drop 200+ bones for it, it'll take you 2 years to re-coop the cost.......  As for the tono cover......... It adds looks to the  truck as well as performance :thumb:

 

My wife drives the truck most of the time, as I comute 40 miles round trip everyday and she does 15.  I think it's my weekend playing that is lowering my mileage  :thumb:

 

What about adding a super-charger?

What about loosing some weight of the truck? Amazing what you could do if you dropped a couple lbs......

Those speakers will certain improve the mileage, and add some horsepower too.

Definately do the K&N Filter if not the FIPK.  The tonneau does look good, however it did little for my mileage.

What about flex-a-lite fans?
