DHP or hypertech
DHP for a couple of reasons....
First, Hypertech does not make a unit for the 3.4L... Secondly, the DHP unit will allow you to dial deeper into the setting of your PCM... Down side, it does require either a very long cable from your PC or a laptop......... If your not into that I would suggest a pre-programmed chip...
