There are no changes that can be made to the reflash. The reflash is designed for a stock car with the supercharger added. Any other changes you make may cuase the car to run rich or lean and you do so at your own risk.

so why does ct-engineering state on their site that:

The addition of Intake, Headers, and Cat-Back Exhaust is Highly Recommended

Try putting your stock intake and airbox back on and see what effect that has. The MAF is very sensative to changes in diameter and shape.
