www.GFchips.com advertise a chip for the Terrain. I know nothing about them, have no idea if they really work and, I am always sceptical about anything that advertises increased milage and power etc. That being said, I am sure there are other folks here that can give an honest opinion. I would be interested in hearing it too as, the milage I get from my 2011 V6 leave me less than impressed.
