96' GMC Jimmy Vortec 4.3L

After hearing about your products from both of my brothers, my husband and I just had to order one. Gas prices are so outrageous here in Alaska that we needed all the help we could get. Well, we sure got it with your AquaTune system. While my brother was here visiting, he, my husband and my son, installed it on our ’96 GMC Jimmy Vortec 4.3L. Prior to installing it the gas mileage was the pits and the exhaust had a real nasty smell. A couple of minutes of idling with the system on, the exhaust smelled clean and crisp, the horsepower went up drastically and, best of all, so did the fuel economy. So far, we are seeing well over the 25%. Sure glad we took their advice.
