I am picking my 2010 Jeep SRT8 up tommorow. I can't wait. I was reading up on some tuners. Hoping to get some feed back. How is the milage with a tune for 91 octane. And the good and bad about some tuners. Thanks :D

I have a CMR DYNO TUNE and run 91 octain and i get 14.2 in town short freeway trips under 200 miles at 65/80 mph i get 18.2.

everyone will get slight difference in milage, depends on how you drive it.if you are a green light mash the peddle and first to the next red light ,you will be different from the guy who occasionally jumps on it.

I was wondering the same thing...it seems with just at CAI and a CMR tune you can see significant increase in gas mileage which would be great.

Can anyone else chime in with their gains im mpg?

Look at my signature photo!

45.7 L/100km or 5.15 MPG!!

and i thought my 9.2MPG was bad

Congrats on the new beast! I was running a canned 91 oct tune from diablo but last week I got an AJ (hemituner) tune and couldn't be happier. Feels like more power, idles better and the shift points are much better. Big improvement over the canned DS tune. With the diablo I was at 11.1 around town with moderate throttle mashing now I'm at 13.

Are you guys kidding about mileage? This is not a Prius.:D

Just fill it up every couple of days and don't worry about the mileage.:D

I get just over 12 all the time (10.5 or so when pulling my trailer). Bone stock. Throttle matted regularly.
