Best tuner for mileage?

Was wondering what the best tuner with a fuel economy setting for an '03 Dodge 5.7 Hemi?

I've heard SC's 91 setting is good, but are there any others that are better

You may or may not see a lot of gain. In your case with the 03, I would suggest the SC over Diablosport due to the trans tuning.

I agree with LX, but don't buy a tuner for solely mileage, you'll be disappointed...

I know. But it's not just for mileage. By the way, would it be a flashpaq or a cortex you're talking about? Do they both let you change shift points?

Besides, I need to get a tuner to adjust for tire size and to change shift points. Personally, I think the shifting for dodge really isn't top notch... Haha

They both have that option as an add-on. The standard tuning makes the shifts "harder", but you must purchase the transmission upgrade to have full customization options like shift points.

I'm pretty sure they did that with the 45RFE and 545RFE to make the transmissions last as long as possible, since it was replacing the god-awful 46RH/RE. They wanted to hedge their bets with the new transmission LoL
