I have the JLT next gen setup as well. I noticed a difference in response first off. It looks better than the stock setup too.
Right before you start your CAI kit install, disconnect the battery. Once you have your CAI kit installed and the MAF connected, re-connect the battery. Now you'll be ready to perform the idle re-learn...
Start the car let it idle while the engine gets up to operating temperature, then wait one minute.
Turn the AC to Max for at least one minute, then turn off A/C.
Then go drive the car for about 10 miles.
This allows the ECU to re-learn your idle and fuel trim strategy.
