Low gas mileage city and hiway @ 4-5 MPG below MSRP sticker data of 15 and 21MPG on a NEW 2013 Silverado. 2000 miles on odometer and mileage not improving.

is this calculated mileage or what the estimated mileage is showing on the dash. Have you checked to see what you get on just the freeway?

What are your driving habits like?

How is your tire pressure?

Do you make a lot of short trips?

My 1197 tacoma 4 cylinder automatic w transmission has little power. I have tuned it up with some increase in power but not much, I average 23 mpg. what can I do to increase power?

You could put in a turbo or increase air flow.
You could buy an aftermarket ecu which is tuned for performance.
You could also get a machinist to make the cylinder bores bigger and put in bigger pistons etc but this may be expensive.
Or replace the engine.

I love my pacifica rides great. I have been keeping track of my fuel consumption (4 l engine) City I average 14.5 l/100 km and on the Highway about 11.5 l / 100km ( 23 mpg). I havve a k&N filter, Do...

The gizmo's that claim to increase your mileage do not work , you might as well hire a witch to cast a spell on your car. The best way to increase mileage is to make sure tire pressures are correct , remove any excess weight (junk) from the trunk , and practice economy driving habits. No quick starts etc.

If I'm installing headers on my 03 silverado is there anything else to consider after I install them like reprograming or anything to make sure it runs ok or can I just throw them on and call it a day?

buy gaskets deffinatly. but no, no reprogramming required. However i do suggest a SUPER CHIP, its a piggy back tool that remaps the fuel and air intake for modified trucks to save MPG and/or increase Horsepower and Tourqe. If you are just installing headers, make sure to tighten the bolts going from the middle of the exhaust manifold(headers) outwords, keeping the tourqe the same on each bolt. otherwise you could lose compression and send a piston flying through your block.

Increase fuel efficiency from 22.mpg

Get an Altima. With all the horse power of the Maxima, not much else can be done but to putter around like an old woman. Could try a K&N filter for maybe a .5-1 mpg increase.

Improve towing

are you looking at improving fuel econ or power ?

fuel econ can be increased by 3-5 mpg by installing a torque converter lock up control gale banks makes a great one but there are others

short bursts of added power can be added by a propane injection system there's a bunch of mfg's of these just google it and you'll see

these are the lowest cost things i know of

of course for more money there are belt driven blower kits you can add
these add 20 to 100 hp and can cost 1200 to 4500 bucks depending on what kit you want

Ohh and another way low cost way to increase both MPG and Power is to increase your exaust pipe size to 4 inches Plus++++ but be carefull
ck your local laws about mod pipes on trucks there not legal everywhere
