I was wondering what i could do to my 99 silverado with a 5.3 to make it faster and more powerful. I was thinking about getting a performance chip but dont know a lot about them so what is the best and what would go best in my truck. Also what else can i do with out replacing the motor and what are some good upgrades for off roading
Thanks,
Jake

 

Well I'm not sure if this would be good for off roading.
