Mpg questions.

[grayduty]

I wanna put injectors possibly 200/30% or 250/200% not sure yet. But I was curious as to what that'd do to my mpg. I'm usually getting about 14(which sucks. I don't understand.) I will be upgrading the turbo and possibly hpop. Any help would be appreciated.

still have the factory exhaust? if so theres part of your problem, i deleted the cat and the muffler i gained 1 - 3 mpgs, haven't had the funds to really know for sure

Stock exhaust is long gone. I got a 5" turbo back. 6637 intake. And chip. But it's lifted 6" with wide 33" tires. I'm just curious about what the injectors would do to the mpg.

it all depends on how you drive.
you should get better mpg with single shots but it will be hard to drive like
a grandpa lol

Haha this is true. I'm just leery about it cuz I travel for work so I'm kinda mpg conscious.

Those injectors are WAY too big for stock turbo. But mileage goes up with modifications typically, if you keep your foot out of it.

Do you account for the 33s in your mpg figures? Your are likely traveling more mileage on 33's than the stock tires, and the odometer doesnt show this.

I will be getting a bigger turbo when I get the injectors. Possible an H2E or a 38r. I'm not sure yet. When I call Dave at swamps I'll ask him.

And no I don't account for the bigger tires. I'm not quite sure how to go about doing that. And usually when I'm traveling for work (500+ miles) I do about 60-70mph the whole way. I don't mess around like I do when I'm at home.

h2e is more like it for those size injectors....
what size were your original tires? My 35's are 5% larger than my stock tires, so when I tally up my mileage traveled, I multiply it by .05 to get the accurate reading from it. If you do lots of 60-70mph traveling, you are off a good deal mileage I would THINK, depending on the size difference of the 33's.
