I dont know much about PCR, I was honestly afraid to even install because of the way it was instructed to set up. They claim to be performance, but:

It changes the reading of the IAT sensor (intake air temp) to show cooler air then is actually entering the engine. The engine adapts by adding additional fuel to compensate for the supposedly incoming denser and cooler air

Bought for my 2011 Charger, but again I never installed it. I dont know if it's specifically for 2011 Dodge Charger RTs or if it can be used on any vehicle, but instructions included are for the 2011 Charger RT
