Hi:
I have been trying to decide what is the best chip to run in mu 03 duramax Lb7. I have installed an AFE stage 2 intake and a 4" Stainless Magna Flow exhaust. once i changed it i noticed a lot louder exhaust noise, but as long as I drive it consistently I see about a 2-3 MPG increase. Now I am considering the Chip. I installed a temporary Freebie Bully dog temporary download and Holy Crap, did it go. It was also much quieter than the factory settings with the download installed. It Drove like a supercharged sports car. three days later when the download de activated, it was a really noticeable difference and the exhaust noise came back. I suspect this is mainly injection timing. the Truck ran much smoother with the Bully dog download as well.
want to put in a chip with in cab adjustability and built in guages, but cannot seem to find out which chip Bully Dog or Edge is better overall and would give the best fuel economy both empty and towing.
If someone has some tips and comments please add them. Thanks
