So far only the 87 tune. I want to try the tow and 91 tunes to see if i notice any differences. mileage went up around 1mpg from average with the 87 tune.

 

Yea I saw that also.
I tried a comparison between tow tune, 87 and Mileage XS and found 87 and Mileage XS were only on average a 1/2 mpg difference but 87 was 3mpg higher then towing. So I recently switched from Towing to 87.

I want to get it to read my transmission temp.... soon?

 

15-18HP and 21-22 torque. It's advanced timing but no shift points. Just got off the phone with Superchips with a lot of questions. I am sticking with 91 tune or tow.... Very similar

 

are any of you running 87 octane with the 89 tune? Is there a difference?

 

I run the Tow setting w/ 87.

No problems so far...

 

I have ran the 91 tune for almost 2 years now. I have gone back to the 87 a few times with gas $$$ and all......but the 91 tune just drives and feels the best.

for the extra $2-3 bucks a tank its worth it to keep a smile on my face

 

I run the 93 octane tune and run 87 octane gas. Been doing it for a year and get 20mpg average. I commute 45 miles one way.
At Rausch Creek I run the crawl tune also on 87 octane gas. Really like it. No surging over rocks the way the stock chrysler tune does.

 

I thought running the 93 tune with 87 octane was bad for the engine? Anyone else doing this successfully?

 

The instructions dont say "engine will be destroyed". Over a year now.now knocks no pings no hesitation. Maybe 93 octane gives more power? My butt dyno cant tell so 87 i run

 

I run 91 or tow with 91 fuel, the past 6 months when gas got out of controlled I ran 87. Glad to say I'm back at 91 at tow setting. I run k&n 63 with afe 3" cat back. Getting an itch for more power and suggestions on what I should do next.
