what does the iNTENSE™ Powertrain Control Module do ???

 

its a pre tuned module that has a custom tune loaded into it

 

buy mine

 

There tunes are only good if you use their kits and only their kits. If you add any other performance parts it will screw up the tune and your car won't run right. Even a CAI. Just by HPTuners and tune to what you have.
