took the car on a 190 mile one way trip down the interstate and the gas mileage is horrible for a v6...

running 93 octane with c&l intake and evolution 93 tune @ 80-85 mph= 22 mpg

Not to bad for a mustang.

In December I drove about 900 miles through DC, Roanoke, Martinsville and back (i.e. mountains). I kept my speed around 72-75mph where possible. I averaged 25.5mpg. I too have a C&L and 93 Evolution tune on my 4.0L/5spd, but I also have 4.10:1 gears! Conversely, my wife's stock 4.0L/auto vert gets worse mileage than my coupe (both city and highway) - go figure!

I drove aproximately 235 miles yesterday and got 27.22 MPG averaging a speed of 75. My car is still stock

your speed is the reason. i know its extremely difficult but try next time at 65-70mph and you should see at least a 5mpg increase. i got 27 with my 91 torq tune after about 100 miles at this speed.

Hey Doug, you're right in the area of mileage figures you should be with your lead foot. Slow down a little and you'll see the figures go up. I have 1005 rwhp in my 07 V6 with many mods and a 4.10 rearend. I get about 29 miles per gallon with speeds around 75 mph. Take care, Jack.

That doesn't soud too bad a mpg for that crusing speed. You also have to consider how heavy your car is when comparing mpg, not just the tune. Not sure if your an auto vert but if so that would be the heaviest 4.0 in stock trim. Then add the PP, leather and the electronics and your pulling a lot of weight compared to a stock 5spd coupe w/ no or limited options. Add in any luggage or passengers your probably over 4,000 lbs. If you were doing alot of elevation changes vs. flat highway that would add another negative against your mpg. [/align]

damn...i dont know what to say to that...other than i will never believe that you have 1000 rwhp with 29 mpg

I think one of the most important factors in mpg is acceleration. I like to punch it every once in a while, but most of the time, I accel really slowly and smoothly to put less wear on the engine, transmission, etc. and to save mileage. Everyone accelerates heavy from the red light, not just folks with cool cars like us. (soccer moms seem to be the worst)
