"I use my 2006 Nissan Xterra to tow a 24' travel trailer and while the Xterra performs superbly, it is always nice to have a bit more torque on tap. Superchips Cortex allowed me to "Re-tune" the Xterra's ECU to allow more low and midrange power for towing, power you definitly feel! The reason I purchased the Cortex over other brands was Superchips quality and the fact Superchips backs up their product with a 2 year powertrain warrenty for the vehicle being retuned!! Power/Ease of use/Quality/Warranty, Superchips has it all!!" —Alan S from Phoenix, AZ bought a Superchips Cortex Programmer for a 2006 Nissan Xterra, 4.0L V6.
