Many 2005+ Cold Air Intakes are equipped with a specially formed venturi (reduction sleeve) to ensure accurate MAF sensor readings. This simulates the factory MAF sizing eliminating the need for a "Tune". This is very common with C&L and Airaid CAI's.
There are many times when completing the tune request form it is unknown if this venturi is still installed in the intake or the tune is created incorrectly based on this being installed/removed.
9/10 times if you receive a tune from Bama Performance and the car does not run at all or does not run correctly and you have a C&L or Airaid Intake this is the issue. Be sure to check if the insert/venturi is installed prior to calling/emailing for assistance.
