Do not like blue glow in car after dark, did stop the stall I was having when it went from 4 to 8 cylinders. It hurt gas mileage a little. The Yukon does seem to accelerate better. It was very easy to install. I am satisfied with the fact it makes me attain the full motor I paid for all the time. I feel it has kept me from trading my car do to lack luster acceleration.
