Performance Chip RS4
I read all kinds of stuff on the internet about performance chips, some good and some bad. But no one seems to have personal experience, just opinions. Has anyone here ever installed a RS4 chip in their jeep. Thoughts?

RS4 Chip
I ordered this chip since it has a money back guarantee with shipping. I got it today and its a little box with two wires coming out of it. The directions have you disconnecting the IAT sensor (looks at air temperature entering the engine) and connecting these wires into the sensor plug. Well that did not seem right at all! Did some research on IAT sensor + chip and found a site that had one of these things opened up. The two wires just go to a resister that tricks the ECU that its colder so it dumps more fuel into the engine. What a scam, its not even a chip. Lets see if I get my money back!
