Just wondering if these are legit, becuase I've heard that there aren't chips/programmers for the trailblazer. http://www.gfchips.com/chevrolettrailblazer.aspx http://autochipsdirect.com/chevrolet-trailblazer--116...

Hey guys I just got a Superchips Cortex for my '07 TBSS 2WD...I put the Airaid CAI on it a few weeks ago and I could tell a difference in performance then..but I just put the performance tune in my SS today and it totally kicks ASS!!...It definitly throws me back in my seat when it shifts now...
