Well i'm new to this forum, but have been on Chevrolet Forums for a while. In the past i've owned a K5 Blazer and a 1998.5 Audi A4. I was and still am a active member of AudZine where i do a good amount of side work for friends and fellow members.
About a year ago i bought my truck as is.
2004 Chevrolet Silverado 1500
5.3L V8 4WD Automatic
17" Pro Comp Alloy Wheels
ProComp 4" lift
Since then i've added the following.
Black Billet Aluminum Grill Insert
35x12.5 Wild Country tires
SuperChips programmer
Cherry Bomb Glasspack muffler after the Y-pipe
6000k HID kit
Pioneer Stereo w/ Bazooka Tube (nothing crazy)
Eaton Posi Rear differential
K&N Drop in Filter
Over all i'm happy with the truck, but it could always be faster. Then again... it is my work truck so i can't complain too much.
