Well the verdicts in as is the performance results. Last week I went out and did the install on the home-made cold air mod and I've got to say it's definitely made a difference. With both the 0-60 3X Voo-Doo mod and the cold air mod, I'm seeing a definite improvement in throttle respose. From a dead stop the Avalanche can now lay down a black streak about 20-25ft! On the highway I can lock in at 70mph @1900rpm with the cruise control. It's definitely worked for me.
