i was just wondering what everybody gets for mpg with FI. i know some think if you are going that route, mpg should not be important but it still kinda of matters to me. i get 20 on country roads driving an average of 60-65. thanks mark

I avg about 16 combined hiway and city, but I have 410 gears too.

i want an X charger so bad i can taste it...

but...

now, i get 29 mpg on the highway, the prospect of 16mpg makes me think twice..

22-23 highway going 70, 20 mpg overall with about 1/3 city driving 2/3 highway.
...unless the foot is ultra heavy, then it drops a little.

(with 3.73's; oh btw, with stock 3.31s, wasn't much different)

wow that is really good for a 300 hp car. must be a tune really helps when you have fi.

Yikes for some reason I was under the impression that FI didn't reduce MPG by much but thats at least 5-6mpg less than what I'm getting on the HWY (on a good day). Best I've ever averaged was around 30MPG highway

That power comes from extra fuel...FI is not voodoo magic...it is just more air and more fuel getting psuhed through the motor.

there are not many cars with 300 hp and 17-20 mpg. That is a bargain!

Gotta pay to play brother!

I go on far too many long drives for that though :P Someday I'll go FI, but only after I'm in a GT :P. 1 month from now I'll be driving 1,000 miles to my girlfriends parents house, then 1K back. The reduction in mpg would probably cost an extra $50 for that trip :P

part of the problem is that when you go fi you play more. i don't remember ever getting 30 mpg in my car. but with my my color dash if i behave i do see 27 or 30 at times on the dash but that is an average. big foot equals bad mileage. i didn't get the car for its good mileage i got it for its good looks. if i wanted mileage i would have gotten a prius!
