How can I increase the low-end power in my 2007 Escalade so that it tows a trailer better?
It seems as though the truck just needs to downshift all the time. And the fuel milage is 6 - 7!!

 

What is the axle ratio on that? My Suburban is a 3.73 and it can pull stumps. Of course a lower ratio will do nothing for your gas consumption. Gibson exhaust makes headers and systems for RV's, SUV's and tow vehicles that move the torque curve down into the 1800 to 3000 rpm range as well. They have a web site. http://www.gibsonperformance.com/vehicle_products.asp You would also get a more aggressive and louder exhaust rumble but certainly nothing to shake the dental work loose.
