Thread: upgrades?

  1. #1

    Default upgrades?

    I just bought A 05' silverado with the 4.8 liter v8. I was wondering if any one had any suggestions as far as squeezing some extra power out of it.

    you can also do some underdrive pulleys, an electric fan and make new engine grounding wires out of 2 awg or 0 awg wire this is a little car audio trick to provide higher amp output and better grounding. But it also does help with mpg and makes your electrical parts last longer and its cheap and easy to do
