is that why you fart so much?

 

Enjoy it.

any updates?

 

I haven't had the consistency in testing that I would want. The weather has been inconsistent, I've made a couple extra stops on the way home, and my brother borrowed the truck a couple times (though only for 5 miles of driving, but the start/warm cycle sucks up gas).

but, as of now, I am not seeing any gain. Apparently Mileage XS does change shift timings, and that's all I really want from the SC, so I'll leave it on there indefinitely until I'm satisfied with the data.

 

**** it! why not get good milage for a truck!! theres no reason why not! who the hell wants to be paying a ton of money for gas when we can spend less, if you can get better milage then by all means DO SO! not all of us have a alternate commuter vehicle to save gas money on.

 

Built in shift points and adjustable WOT's are common to all 4 canned tunes. As well as the line pressure increase which maked the shifting a lot firmer.
I saw a solid 2.3 mpg increase on the XS tune on my last Ga trip, but didn't like it, the truck had no *****! Except for better tranny shifts, the truck felt weaker than stock. That was my test run, would have gone back to stock when I got to the farm anyway, but I'll not even change it for highway driving again...

 

I just stick with the 91 performance tune. It gives me the best mileage anyway so no reason to ever change it. That is until they come out with the 93 tune.

 

That's what I think dude. So long as you don't sacrifice all of your power, why the hell not get some better mpgs? These fuel costs really do suck, and isn't always fun to pay.
What would happen if a vehicle would have an 87 tune on it, then run off of 89? Just worse mpgs, power, or what?

 

i have the 87 tune set and i run on 89. i havent noticed a big difference in mpgs up or down but this is my first tank. power though is increased

 

shouldnt the truck run better on higher octane at least?
