The only thing I can think of is the Osiris tune. One of my 5 maps is a "fuel saver" setting. Other than that adjusting your driving habits is the only thing you can do.

 

Damn I figured a cai would help, usually does on most cars.

Anything specific needs to be done to the car for that tune?

 

Have you done a tuneup? Trans-fluid, plugs, etc...

 

I was talking about a custom dyne tune where they reflash your ECU. Ash has good ideas^^^

 

How do you know what ballast is safe on a car my girlfriend has a scion TC and I'm trying to figure if a 35w ballast is ok

 

if you do not go over 2 you are not giving enough gas, shift at 3k or less. Staying on the throttle too long will get you poor mpg, what MPG are you receiving now?

 

Anyone know how to fix this? I keep tucking it in but it keeps coming out, This is on the door.

 

Well I drive 2003 g35 sedan automatic.

Full tank will give me about 300-310ish

 

Try a fabric glue

 

I get 320-330 miles a tank in mostly spirited, almost all city driving. You might get better gas mileage if you upped the revs a bit.

 

Miles per "tank" = meaningless number.

Fuel Economy is measured in MPG (Miles per Gallon)

 

Ok so i bought some headlights but they are halogen (h1 bulb) and i have the stock hids on my car (d2r bulb) so i was thinkin can i buy h1 hid bulbs , cut the wires from them , cut the wires from my stock d2r bulbs , and put them together so they work with the stock ballast, that way i have h1 hids. Would this work? I dont wanna go thru the mission in buying new ballast and all that stuff.

Ps. I know is gonna make the glare but w.e

 

95% of the time I do highway driving.
I upped the revs a bit today and actually saw my gas go down quicker. I'm clueless

 

sounds like you def need a tune up. my car modded get better gas mileage while doing alot of spirited driving..

 

I get 20.xx mpg pertank consistently, thats a little over 400 per tank.

Stop at 3k, give it some gas. If you been granny driving this whole time you need some time to learn
