best mileage with the sct.

[coolman3030]

i recently purchased the sct x3 with custom tunes... truck hauls *** just wondering what i should be driving around using... i dont usually pull anything. i have a street, extreme race, and tow tune, but what about strategy tune? what is that. and i also have return to stock. someone give me some pointers i would like to save diesel here. thanks

My understanding is that the hotter the tune the more efficient the truck is ***IF*** you can keep your foot out of it and keep the speed down on the highway.

When I had stock tires I got 22mpg on all highway slowish trip.... averaged about 60mpg and got what I considered to be GREAT mileage. On a fast trip ~80mph I'd get about 17. Now that's I've increased the size of the rubber (35x13.50) my mileage isn't nearly as good...

ive got 35's on it... damit. hopefully i can get better than 12 which is what i got when it was stock. but we will see. im just gonna run it on street all the time and see what i get for mileage if i can keep my foot off it. unless anyone has any other suggestions for best mileage???

my best milage is def with the extreme race tune.

Are the hot tunes ok to be used as daily drivers?

Your best mileage will be with the race file and it is ok to use it as a DD. I have been using Extreme street as my DD for the last 40,000 miles. I average 16mpg with mixed driving

I'm getting 14.6 on my 2007 F350 S/D 4X4. Using a street tune for everday driving from DJ's on my X3. I get @ 13.0 in the tow mode pulling a 32' 5th wheel. And in the street mode on the Interstate I can get it up to 20+ MPG after about 50 miles and it settles in. Good Luck

thank you. well i will give it a try on street. extreme is too tempting for me lol.

I drove home from Florida to California with blown head gaskets, drove 65mph all the way home, 38" tires, 8" lift and got 15.2mpg with extreme race. My guess is without blown head gaskets it would have been better. I took my truck to the dealer in florida 3 times in a month for coolant puking and they screwed me all 3 times, even right before my drive across country. Which pisses me off because I could have been stuck in the middle of nowhere if my engine blew up. When I got home my degas bottle was dry and I took it to the dealer in town and they replaced the egr cooler and oil cooler and called and said I had blown head gaskets. It's still in the shop, but I'm eager to see what my mpg will be when it's all fixed up. Thought I'd share my story.

my best mileage seems to be w/ ID street tune. I can get 21 mpg at 60 mph

[coolman3030]

ID did custom tunes on mine aswell. we will see what the mileage says. thanks
