1. Does the 93 cobra have 19 or 24 lb injectors and maf sensor?
2. Do you need the computer calibrated to install the 24 lb injectors and MAF? Or can I use the stock computer?
You need the computer calibrated if your car currently has 19 pound injectors. If money is an issue it would be cheaper to get a MAF that is calibrated to 24 pound injectors rather than having a custom tune done. Custom tunes usually run in the $300+ range and you can pick up a 24 pound MAF for less. The custom tune is the preferred way.
