hi. im new to the site. i see alot of guy saying they performed all of the free upgrades. i havent done a thing to my 02 silverado 4.8 ext. can anyone help me with these upgrades. this isnt a race truck. actually a tow vehicle for my camaro but i would like more performance. thanks

 

If your reffering to free mods... http://www.installuniversity.com/ins...sity/index.htm

Go there. Some of them you can do to your truck. However, most of it wont help greatly in power. If your looking for power to tow around a vehicle. It would almost benefit you more to go ahead and get a bigger truck. Possibly a 6.0L with the 4l80e tranny.. like a 2500hd. But if you want to put money into the 4.8, you can of course do exhaust, long tube headers from http://www.texas-speed.com/, you can do a cam swap, PM me if you have any other questions.
