Is Better Fuel Economy and Smoother Shifting Gained with the Edge Programmer on a 2005 Suburban

Expert Reply:

I did some calculations for you that may help with your decision to purchase a performance programmer based on fuel mileage increase. Many Edge customers see mileage gains of 4 to 5 miles per gallon when using the programmer, # EP85150, in the economy mode on their vehicle. I would say that it is a safe bet to say you will gain at least 2 miles per gallon in the economy mode.

At 2 miles per gallon, your increase would be 12.5 percent. Lets say you go from 16 to 18 MPG. With a 30 gallon fill up you will be able to go 60 miles farther under normal conditions. At 4.00 dollars a gallon this equates to approximately 12 dollars per 30 gallon fill up.

At that rate it would take approximately 36, 30 gallon fill ups to re-coupe the price of the Edge programmer, which equates to about 18,000 miles. If your driving style and conditions yield better than 2 MPG increase, the number of miles to re-coupe the cost of the programmer will significantly decrease.

The programmer changes transmission settings in all modes and will provide firmer shift points, by increasing line pressure.

Two other items that will help with fuel mileage would be a aFe Direct Fit Cold Air Intake System, item # AFE51-10092, to let the engine breathe better and an exhaust system, like the MagnaFlow Stainless Steel Cat-Back Exhaust System, # MF15665, to allow the exhaust to escape easier.
