Well I drove to Phoenix today from Yuma which is almost a 200 mile trip oneway to catch my D. Lions while they were in town(and Lost). But this morning before I left I switched my sc tuner to the economy/stock mode to see if I would get any better MPG... on the way there I got about 14.8. Then on the way back I switched it back to the performance mode and I got about 14.6. I really could tell a difference between the two (performane wise) also and with that little of a difference I will be keeping the performance setting. I did the calc. by hand also before anybody asks. I was running about 80 mph and my tach was at 2250-2300 just about the entire way.

 

It isn't the small differemce in MPG that gets me, it's the 20 cents more per gallon for premium.

 

I'm already running midgrade anyway so it is only about 10 cents.

 

Negative 18 yards rushing! What's up with that?
Crazy year ain't it? Teams look great one week and can't do anything right the next week. You take New England and maybe 2 or 3 other teams out of the picture and you have complete parity. No clue who can beat who on a given Sunday.

Oh, and about the SC Tuner, I actually clocked it on a couple of trips to my GA. farm last year (a shade under 300 miles each way) and early this spring. I got .2 mpg's better with the economy once and .1 mpg's better with the performance once. So, mine stays on performance all the time. This was running 93 octane gas in both settings.

BTW - I also clocked the 87 economy tune with 87 octane on one trip and got 1.7 mpg worse! So it really doesn't save you anything by not putting 91/93 octane in the truck.

 

I'm with you HammerZ I could not believe they lost and this was my first pro game ever attending and this is what happened!!! I think I will stay at home next year and save some money. Anyway I did have fun and it was a nice drive in my truck. It really performs well on the road, not as smooth as my wife's Tahoe but still really nice for a truck. Wouldn't trade it for nothing.

 

i always have my chip on performance.... ill be calculating the "gas mileage" when i get run lower... i only used a half a tank so far...

 

You know I have ran both the performance tune and the econo tune in my truck and I got to say I prefer the econo tune over the performance tune. From what I have seen the perfomance tune is really works great for the upper rpms and puts me at 14.9mpg but the low rpm rang feels like the stock. On the other hand with the econo tune (running 89 octane) gives me much better performance in the lower rpm range than the performance setting but lacks slightly in the upper rpm range and give me 15.1mpg.

 

When i had my tuner i was getting about 18 mpg on both performance and ecomony mode
