poor fuel mileage need help
 

alright i have a 02 auto with a 4 inch exhaust, k&n filter, Quadzilla Altitude with the pulse meter. im aver 15 mpg all the time thats with the programmer turned up and on lev 1 dont know what could be wrong i also have a air dog 150 fuel system

fuel filter, air filter, right foot???? mine gets about 18 city normal driving but if i get on it often it can vary.

new fuel filter and jus cleand air filter and been drivin like a 90 year old granny. dosnt matter if im runnin the balls off of it or takin it easy still get 15 mpg

Shorts trips will get ya

Right foot and mileage are directly connected.[coffee] The more the right pedal is pushed, the more the mileage will drop.:o Ease up on right foot, and mileage will come up.:cool: Remember the wise old saying, you play, you pay (in more ways than one).

Has your area switched to winter fuel? I drop about 4mpg with winter fuel. Try a winter front (cardboard) to get the engine temp up quicker - this has helped with mine.

you might try cleaning the AIT and MAP sensors to see if that helps? Have you checked for codes?

gear ratio? and yes, city vs. hwy makes a diff.

im running 3.55 gears with 285/75/16 tires. the skinny pedel stays off the metal all most most of the time. im thinking it might be something in the timeing. i had a inj pump put on about a year ago and ever since then my towing power went to crap. it runs good with out a load but soon as ya put something behind id it falls on its face.

i cecked the codes today only one i have is a 0500 and thats for the vehicle speed sensor

Considering your running a different size tire than what the speedo is calibrated for your odometer is off.
Oh ya you have the Adrenaline correct? Edge sells the Attitude.[dummy]
Which tune are you running? You can set the Pulse up to read the correct MPH. You have to input the stock tire size and the new size.

ahhh yes different size tires make a big difference. on my bronco i have 33s on it and i was getting 10 mpg according to the odo. i checked it with my gps and i was getting 14 mpg. the gps was on the money. i felt like a goober after that [duhhh]. cause i been woundering why i keep getting 10 mpg with a 351 with cam heads headers exhaust intake performance coil advanced timing and so on

ill have to check that never thought about the tires screwin with it . i dont know really what settins im runnin on the quadzilla. i emailed them about about information on custom tuning but they didnt geive much info

Just one quick thought is tire pressure. You may want to check the pressure more often with the larger tires......more road contact.

thanks i usely check them once a week im thinking there is something wrong with my quadzilla programmer im gettin a real bad miss with im about mid throtle dont know what is goin on with it
if got a 0622 and a 1693 codes showin
