Does anyone know of any company that makes one of the super chips and tuner for a gas Hemi engine? I have a quad cab 4X4 5.7L pulling a 27 foot travel trailer (ultralite) and am getting less than 10 miles per gallon while towing. I get around 14-14.5 while driving solo.

Thanks Crazymo. I had just about given up hope of anyone answering my question. Do you have either one of those on your truck, and how does it work if you do?

The gas engine tuners are nowhere near as effective as for a diesel. It is hard to get more power out of a gasser without advancing the timing--this requires premium fuel, and the extra cost for gas will negate any fuel mileage increase. At least this has been my experience with a Ford V10, maybe the tuners have figured out some other way now.
