This is definitely the first product to get when deciding to upgrade your vehicle. The Extreme performance mode knocks at least 2 seconds off my 0 - 60 time and for around town driving the fuel economy setting is great. I own a 2002 Silverado with the 4.8 and I get up to 24.3mpg! This thing pays for itself in less than a year and I would definitely recommend it to a friend.
