Default Looking for a tuner - Need advice

I am wondering if there is a tuner out there that lets you switch between driving and hauling modes. For example is there a mode for regular driving that increases fuel economy, and a different mode for hauling/towing that increases power and shift characteristics?

If not, is there a good overall tuner that will give me more power plus better mpgs, or are those 2 not allowed in the same sentence?

Is the increase in mpg on these things enough to make them worth the $300+ you spend on one? We have gas from 87-91 octane. Do you get better fuel economy using 91 and is it worth an extra $0.15 per gallon?

Thanks in advance.

BTW it is a 2009 5.7 V8 Hemi and 3.55 axle

check out superchips they have a tow setting as well as the mileage but from what ive experienced the performance setting gives better mileage as long as you dont have heavy foot syndrome lol...

2 inch leveling lift 3 inch body lift, 34" bfg mud terrain TA KM2, straight pipe, vararam intake, superchips cortex, Firestone air bags, skyjacker n8000 shocks rear, s8000 front struts, painted head lights, tinted tail,cab mount light, big shiny chrome balls.

Edge may have one for the hemi now..when you switch between modes you have to stop, select the new mode, and wait for the unit to boot up.

I like the DiabloSport Predator a lot. Combining that tuner with an intake and exhaust got me some nice gains and a 4+ MPG highway mileage gain!

You can see the before and after programmer install dyno results in my Ram Mods link below, on page 2.
