[whitemustang02]

im geting a little 0ver 22 and that is with me on that gas havy and i think i should be geting a little better

[Avaric3]

could it be because my check engine lights on because my front 02s are disconnected? thats prob why

tru lol, ill get right on putting those 02 extenders in!! and in aweek ill get back to you guys and let ya know how my mpg is. and also, i have lt headers, dont they make you run even richer? should i use my tuner to lean it out 2% or so?

[tjames]

if you fix the 02s that should fix the problem. if its not affecting your driving that should be fine

[AtlanticBlue99]

its a 15.5 gallon tank, not 15 gal. and i get 20mpg with full bolt ons

[97TunedMustang]

i get like 16-17 but then again i have more then your standard bolts-ons... i think my tune sucks to and theres only so much you can do with tuning non intercooled. but hey im workin on that

[silverbullet17]

i got a 99 and im gettin like 15 haha that sucks. i just got my sct custom tune on so hopefully i'll get a little better and im thinking bout doing seafoam this week.

[Avaric3]

the sad part is is that im getting that mpg w/ uderdrive pullies and a tuner

[Onemanzu]

I get 14 but thats because my car is fucked up at the moment... i used to get close to 23 before i started working on my car about a month ago

its all the o2 sensors man. once you get those fixed you should be back to normal. cant you use the tuner to shut off the need for the sensors?

[02stang02]

whats sea foam and where can u get it? and how do u put it in? can u put it in ur self?

[Onemanzu]

engine cleaning agent
auto zone, napa, o'riellys
through the vacuum, oil, and gas tank
yes

[tjames]

if you put it in your oil your supposed to get it changed within like 300 miles

on my old diablosport predator, i could turn off all 4 sensors, but w/ the sct xcal 3 it only lets me shut down the rear 2
