i have a 03 v6 mustang i have fixed two magna flows and straight pipes from the orginoal headers but i noticed that the car fuel consumes increases it was 200 per 10 galons , is it alow range , and i dunno if it was 200 miles or kilometers so plz help me ? and it consumes alot what i can do to ruduce it ?
Whoa, that is questionable gas milage. What other mods do you have? How are your tires? Worn or new? Properly inflated? Alignment in good order? Are you running the AC constantly? Do you have a 300 pound speaker box in the trunk? Is this city or highway milage? There are quite a few factors that can affect gas milage including the brand you use.
it is city , no other modification on the car and the tires are new.. and i use the a/c but normal use ... and plz tell me the electronic milage numeris it in miles or kilometer?
Where are you? If you're in Canada and you're speedometer is in kph's, then the the odometer is in km's. But if you have the standard mph speedo, then it's 200 miles. Assuming the car is an automatic, 20 miles per gallon is about normal for aggressive city driving. I used to get anywhere from 18-22mpg if all miles were in the Orlando area. Driving around here is 0-60-0-60 with all the traffic, and everyone drives aggressive. Brakes, tires, and gas, all get burned fast in this city.
it me again thankx for all the replays acctuually i didn't remove any sensiors at all but i have new problem now the dashboard shows the ( servise engine soon ) i went and changed the oil and the oil filter but this sign didn't go off so i am lost wht happened to my car? This is my first mustang so plz be paitent with me... thankx
More than likely your straight pipe setup, pull the codes from the computer to see what is throwing your engine light.
- acctually i did remove the battery for about 7 hours and reconeccted it again and the -serveice enginge soon -mark has gone ..... is wht i have done is the right thing ? and i am thinking of putting k&n air filter so shall i put only the filter or the whole system , and would it increase the hp of my car and wont cause me new problems ?... thankx for helping
All you did was reset the computer. If you did'nt fix the problems, the check engine light will come back on again. A CAI or drop in K&N filter will garner you some hp, but not a whole bunch. You probably should look into getting your Check Engine Light issue fixed first before doing any more mods.
