Stage 2 tuning is for a turbo or supercharger configuration. Wideband airfuel loggers are needed to tune this setup. Hemifever Tuning supports 1996 through 2006 SCT supported vehicles. Verify your supported vehicle in the Technical Specs
The SCT XCalibrator 3 can store up to 10 Custom Tune files, while storing the stock factory tune for easy restoration back to the stock configuration. Custom tuning is required if you have installed a turbo or supercharger. Stage 2 is also needed for open loop tuning. I'll work with you and email tunes to get your vehicle running its optimum in the current configuration. Once tuned, changes that you make which require additional tuning will be subject to additional tuning fees.
Idle, timing, and fuel curves can be changed to remove rich engine lights or fix idle problems. With a 2 bar map sensor and large injectors, we can dial in your forced induction configuration.
