"Perked up my Duramax. I'm still playing with the settings. Havent checked the miliage yet. Hardest part of the installation was drilling & taping the hole in the manifold. It would be easier if done on a hoist. I have ordered a 4" exhaust kit to complete the package." —Edward P from Fort Morgan, CO bought an Edge Juice with Attitude CS or CTS for a 2003 Chevy Silverado.
"Even on level 1 do you notice huge gains in power. I have an mbrp straight pipe exhaust which gave me turbo lag but with the edge juice with attitude it took it right away. Sometimes takes a minute for power to be noticeable when you first jump in. Also takes the transmission a little to get used to the huge power gains in the upper levels. Otherwise I love it.

"Wow. Unleash the beast. I couldn't believe how much I was limiting the power of the Duramax until I installed the Edge Juice with Attitude. I have only used it for approximately 100 miles to play around with the different power settings. Can't wait to put it to the test with 12k lb. fifth wheel load." —Kory T from West Jordan, UT bought an Edge Juice with Attitude CS or CTS for a 2003 Chevy Silverado, 6.6L Duramax.

Once torqued down it works great, better mileage and horsepower and with the price of gas where it is it should pay off in no time." —Kim B from Mount Vernon, IN bought a Jet Performance Module for a 2003 Chevy Silverado, 2.2L CPI 4-cyl..
