Works like it should. Haven't dynoed it yet but I'd say maybe 5 hp gain. Worth the price. Easy installation

Had a few issues with the install because of the cold air intake. Decent product, though. The whistle sounds pretty cool, kinda like a poor man's supercharger. Haven't run a full tank through it yet, so no estimates on the mpg increase. Feels a little more responsive and seems to run at lower rpms from 45-55mph. Shipping was super fast! Got the email that it shipped Monday morning, I had the product in my hands on Tuesday afternoon. Love AutoAnything!

over all it helped with low end torque but did require me to modify my cold air intake a bit cause the clutch fan grazed it. i got a little more hp but nothing as far as mpg. It makes my 2001 2500HD 6.0L sound like it has a supercharger! would get for other vehicles
