Great tuner, easy to install, great power out put without shedding and busting up the drivetrain and throwing extra fuel out the tailpipe. Really wakes up the truck. Mileage has improved 2mpg. Does everything I need it to do.
Great tuner

I have a 2004 lb7 duramax. The tuner was easy to install. You can feel the difference on each power level. A great choice for the guy that doesn't like to grenade drive line parts and transmissions and lets the truck run within its means. The one big reason I decided on this tuner is because it has trans back down so you don't toast it. Doesn't put out any more smoke then stock, which is fine by me with the cost of diesel where it is. works great for what I need it to do.

I used to have a mustang gt with a dyno tune on it, and after putting this thing on my LB7, it put my mustang to shame, it will literally pin you to the seat. Provides great fuel milleage on the highway, around 20mpg, and tons more power, it is almost scary how powerful it will make you truck. Well worth the money.
