Main reason for my purchase was to give my 2007 Chevy Avalanche a little kick when either accelerating from a dead stop or getting onto a freeway. Being only a 4 speed, I noticed my Avalanche "lagged", for a lack of a better word, when getting onto a freeway and trying to accelerate to freeway speeds. I wasn't expecting a huge boost, but I definitely noticed an increase in power when I put the pedal down. Fuel economy stayed the same if not increased, highly recommend this product.

Only had it a month but seems to work. Most times I can tell an improvement in response. Mileage has stayed the same...at least what the computer mPG shows. However sometimes truck still seems to be on 4cyl.... But I think this might just be the power robbing 6 speed xmsn...
