08 Sierra Denali 6.2 Texas Speed 2.2 VVT Cam
Thought I would share a sound clip of my brothers Texas Speed 2.2 VVT cam in his 2008 Sierra Denali. Most people recommended removing the VVT, but thought we would run it with it to see how it feels, which is pretty good. Installed new phaser, phaser limiter, double valve springs, and hardened pushrods.
Cam Specs: 227/239, .629"/.629", 113 LSA
Has Speed Engineering long tubes with their header back kit with dumps before the axle. Obnoxiously loud! Also did the flex fuel pump, FPCM flash, 50# injectors, and flex fuel sensor. It ran 13.8 with headers, Circle D 3200 stall, and a flex fuel tune I did for him.
Going to the track tomorrow to get some new track times.

Thanks.
105.66 and a 1.87 sixty.
I think with a little more work on the tune and a better launch, maybe 12.7's?
The K&N cold air kit is a restriction. Down to 96 KPA at the top of third gear. Going to do a 4" intake and cartridge MAF which should help as well.
