Depending on the performance parts you're referring to, you may or may not need a custom tune. You'll always benefit from a custom tune, even with a bone stock Mustang. There's plenty of adjustments to be made to a stock car to improve throttle response and power throughout the RPM range.
A dyno tune is usually only necessary when your Mustang is heavily modified with a supercharger or turbo. For any bolt-on mods, a custom email order tune will work perfectly and just as efficient as a dyno tune, if not more efficient (depending on your tuner).
What kind of mods are running or planning to run?
