I immediately saw a hugh gain in horsepower and toque. And the whistle is hardly noticable with my Volant air intake. Great product.

Installed this on my 04 gmc Sierra 6.0 and notice a great low end tourqe increase and gained 2-3mpg with every thing stock except my superchip tuner. Took me couple minutes to install and very well pleased with the overall purchase.
