First off, go through it and fix any worn out stuff. May some cosmetic mods if you like, although mostly these are kind of crappy looking to me. There are probably no worthwhile powertrain mods for the in-line six used in the Trailblazer. Cold Air Intakes make a bit of noise but usually no extra power.
