Your Airaid intake is not compatible with this kit due to the fact that Vortech uses their own inlet tubing. However, you SCT device is compatible, you would just need a tune file from either us here at Stage 3 or Bama. As far as fuel upgrades go, you don't need a new pump unless you're planning or getting a smaller supercharger pulley or other upgrades. You will need upgraded injectors, but the size is going to depend on your Mustang's other modifications and your future plans for your Pony. Buying injectors twice is not exactly easy on your wallet if you upgrade this system and your car down the road. Give us a call at 1-877-578-2433 so we can get a better feel for what you need.
