Before the mods test is done. I have run 2 tank fulls of gas to test my city only mpg before I put on all my mpg mods. The average between the 2 tanks is:
19.32 mpg -city (with radio on at moderate listening volume and driving normal with occasional passing)

I will try and get all the parts to help mpg put on as soon as I can(all have arrived). I will post after results then. Highway mpg I will just calculate through change in rpm's from economy tune and weight loss or I will run a test like this one. Just giving an update.

 

sounds good. keep your testing consistent and descriptive. these results could be very useful to many. good luck.

 

I didnt know the Radio made a difference in your MPG.

 

Radio-I don't know, I here electronics might play a little part in mpg so I thought I would list it.

Yes I am trying to keep everything as precise as I can with the mpg checking. I'm keeping the same driving route, same driving times, and same driving style. I need to get these parts installed so I can finish my testing.

 

I could understand AC but Idk why radio would.

 

just subscribed to this thread!

good luck. i know this will help a lot of people

 

ROCK music, played moderately loud, deffinately changes my gas mileage.....

I think it has something to do with the weight of my foot when Disturbed is playing.....

 

i have a 2007 v6 but i only get 16.1 mpgs but it could be because i like to drive a little fast but still thats a big difference

 

MPG! Blah! If I could drive 100mph to work and back everyday I would.

I think I will get "MPG LOL" on my license plates

 

Thatd be awesome.
