jdyowa Wow. This is some great info. Thanks everyone. My tires hopefully will go on saturday, so I'm playing around with the stockers now.

JTPhoto JK If you go to the Superchips forum you can request a 91 octane vs stock graph.
91 octane tune 239hp and 268ftpds torque.

rics1997 Here is a post I did from 2 years ago. Not a perfect test but this was the results I got.

Ran all tunes (except tow and crawl) starting from the exact location taking the same route and resetting the computer est. MPG each trip. I know the computer isn't perfect but following the same steps it should be close.

My route includes a 17 mile loop. 1st mile was community with some steep hills with a speed limit between 20 to 35 mph. Miles 2 through 8 was 4 lane highway 65 mph. mile 8 through 12 was 45 mph 4 lane with 4 red lights and last 12 through 17 miles was back roads at 35mph.

Now all the tunes worse MPG was in the first mile of this course. The mileage XL was the worse tune by far, it hated stop and go and any hill brought the MPG's down fast. On the highway it slowly creep up in MPG's and may have done better if ran longer on highway. I think it is for long highway trips. City it was real bad though.

My data which includes lowest MPG during test, highest MPG and ending MPG at 17 miles.

Tune............Lowest MPG......Highest MPG........Ending MPG

Stock.............14.1.................17.2....... ...........16.6
Mileage XL......13.7.................16.9................. .16.6
87 tune..........14.5.................18.4........... .......17.6
91 tune..........14.0.................18.2........... .......17.4
93 tune..........14.2.................18.1........... .......17.5

Realizing I ran 87 octane gas for the whole test 87 tune won out easily. 87 made best MPG the quickest and ran over all better. 93 Octane did seem to shift better though and was the only thing I seen that beat the 87 tune running 87 octane.

rics1997 I ran tests on all the tunes and found that 87 tune done the best over all as far as gas mileage. Didn't really feel much response difference in any of them. Superchips posted a Dyno of stock vs 87 tune but didn't post any other tune dynos other then 87 tune.

Always leery of non independent dynos because you don't know all they did but this is a dyno posted of a supposed stock and 87 tune dyno

JTPhoto JK I change it up once in awhile but generally like the Tow Tune which will work on 87 or 91 octane but is most fun on 91.

keycat02 I've tried several of the tunes but like the tow tune best. It seems to downshift more easily and upshifts later as you accelerate.

What tune are you running? (Flashpaq)

I have searched high and low but it seems not many people are talking about this in great detail.
What tunes have you tried and what are you running with your Superchips Flashpaq?
