Have you tried looking here yet? Click Me. If you have you would see that the SCT XCal2 seems to be the best and most popular handheld tuner available for the 03/04 Cobra.

As for a handheld tuner being the most important and first mod for a stock Cobra? No way.... A good CAI & cat-back exhaust provide a million times more return for your money on a stock Terminator than a programmer.

Have you read the 03/04 Cobra FAQ yet?
