I posted this in the Diablo thread, but I'm not sure it really goes there since I'm asking about all tuners. Nobody answered me there anyway.

I have an 05 Ram 1500 Hemi. I'm currently getting like 13mpg. Which of these tuners will best help me with fuel economy? I currently only have a custom dual exhaust on my truck. I'll be putting a CAI/Ramair on it soon. Right now I just primarily want some better mileage. Any performance is extra bonus.

 

A programmer is not going to get you much of a gain in mpgs.

 

Agreed, however I would say Superchips would be better for mileage tune but it is minute IMO. Performance + better mileage dont go together BTW.

 

Performance and fuel economy do go together. If an engine is running more efficiently, then it gets both power and mpgs. Maybe I'll go with a Megasquirt. More work, but then I'll get what I want.

 

WTF is a Megasquirt????

All I was saying is that you will not get a significant improvement in MPGs. I did gain about 1-1.5 MPG with Diablo and about the same with SC when I ran it. I got the most improvement with the 93 DSP tune and the 91 SC tune. The 87 tunes made no improvement, and SC's mileage XS tune made no difference at all.

 

Megasquirt is a DIY ECU that has unlimited tuning capabilities. I just need to know how it would work with the Auto trans before I build one.

1-1.5 mpg is definitely a good improvement on fuel economy. That's an extra 35 miles to the tank for me.

If I decide to go the Megasquirt route, I will make a new post on that. Maybe then I can pull everbody into the MS Cult. (megasquirt, not microsoft)

 

would you be able to run with the ms because of the 16 plugs? i know a few people that have built many ms boards but for bmws not dodge. keep us posted would like to know
