After all the mods I have done I'm only getting 11.3 MPG ! What am I missing here ?

 

well are you a lead foot?

 

Hey man, be happy. I was getting 10.

 

Not a lead foot at all ! And actually I got like 13 to 14 before the mods. And the truck is 99.9 percent of the time empty.

 

Well now you know that mods dont help mpg... Most mods that help mpg are in peoples heads.

 

did u retune ur truck, i had to when i got my true dual exhaust b/c of air/fuel ratio got all messed up

 

... ? disconnect the battery? so the pcm will relearn??

did the o2 sensor get hurt when you put the new cat in?

 

Hows yourplenum gasket?

 

I believe exhaust modifications assist a vehicle in gas mileage once it plains out, but other than that, a big engine is a big engine. Right now I am getting 14 city and 19 highway with 285s. Once the truck plains out, you can just feel the gas pedal becoming very light. The headers and free flowing exhaust really allow the engine to breathe.

 

And according to my computer, I'm getting 14-16 highway and 12-13 in the city. But its wrong, and so is yours Neon.

Do the math buddy. I got 11 mpg when I filled up last, 95% in town. Last time on the highway, 13, from a drive from my city here (Sioux Falls, SD) to Rochester, MN, and back. Filled up when I got there, just over 13 with a big head wind. Used crappy 87 octane (10% ethanol) when I was there, and on the way back got just under 13 with just a slight head wind.

The computers also should be adjusted for the mods, and I'm not necessarily talking just a reset. You need a tuner of some sort, probably SCT is the way I'd go, to let the computer take advantage of the mods. Especially if you are a victim of the "death flash."
