3800 What do you get highway mileage?

[slow04ss]

Took a long highway drive, and I got a true 25mpg(no stopping except to refill gas). I was hoping for a little more. Atleast it's better than the 8-14 I get with the other car

Just curious if this is what to expect, or something is off. Remember this is not chicago i90 go fast, go slow, stop at toll. This is wisconsin i90 where you just cruise at 65-75 for 2 hours

If im on coast get about 28-30 not touching it at alll........country/open roads.....

Use to get about 32mpg but I then got 3.29 gears.

well some of us have custom tunes for gas mileage so it will vary. when i had the T-4 still on the car and i didnt go under boost i had 33-37 with cruise control on.
now with the the paperweight back on top of the motor im about 26-29

what mods do you have? they will effect your MPGs
best way to help is to have scanner like the intercepter to watch timing and you will figure out how to drive(feeling where the sweet spot on the throttle is) with the timing always pretty high.

When I got to Indy I get about 32MPG But If there is a head wind about 28MPG or so. and thats going 80-85 (Speed Limit is 70)

I think When I had my old 99 GP I think I got around 20-23 MPG on the Highway

Now that its warmed up aroind 70-75 I get between 28-31mpg. Probably running a little rich too.

I got around 25mpg when I made that same drive you're talking about. I'm in the south suburbs and drove to Minneapolis from 39 to 90/94 all the way into the Twin Cities. I would've made it one tank of gas but I was getting low around Eau Claire and didn't want to chance it. I knew that exits for fuel aren't as likely there as they are in the Chicagoland area.

When I came back, I did make one stop in the middle of nowhere in Wisconsin to take a leak but I didn't refuel. Pulling back into my driveway, I still had a couple gallons left with 448 miles on the trip odo.

Wow, something must be wrong with my car then. I get about 22mpg consistently on the highway. The car is stock.

Some of the basic mods (PCM, Intake, Exhaust) helped me get Better mileage than stock.

I've got all of you beat...the past couple of months my SEEi is getting about 13.2-16.4mpg. The mixture of cold weather, winter gas, EGR delete and remote starting to warm up is taking it's toll on my mileage.
