Stage 3 Custom Tune - For Naturally Aspirated Mustang
Some aftermarket performance parts (like cold air intakes and headers) change air flow through your Mustang's engine. In some of these cases your Mustang's stock computer settings must be changed so that other engine systems can work effectively with the increased air flow.
Stage3 Motorsports delivers custom tunes right to your email inbox and provides over-the-phone tech support to make sure you are getting the most out of your Mustang's aftermarket modifications.
In order to re-tune your Mustang's computer settings you must have a tuning device. Stage3 Motorsports builds custom tunes for the SCT X-Cal 3 tuner. If you do not already have an SCT tuning device and you need a custom tune, you should see our custom tune w/ handheld SCT X-Cal 3 kit.
If you do already have an SCT tuning device, you should order this product, and someone here at Stage3 Motorsports will contact you within one business day to discuss the specifications of your Mustang. These tunes generally take 48 Hours to show up in your email inbox after we have gathered all necessary specifications.
This custom email tune is for naturally aspirated Mustangs only. If your Mustang is supercharged, see Stage3 Motorsports' Custom Tune for Supercharged Mustangs.
