free mods??

i was wondering what all free mods people have done?
or just list them:devil:
thanks

Start here! www.installuniversity.com click on LSX vehicles then click install documents on the left. Start with free ram air mod then go to cooling system and look for throttle body coolant bypass. The throttle body coolant bypass is not a free mod the parts can be bought for under 10 bucks, thats as close to free as it gets.
