The Hypertech PowerStay is a simple plug-in module that eliminates the annoying Auto Start-Stop and/or cylinder deactivation (V4 mode) on many newer model vehicles. Although these features are touted as fuel mileage-improving features from the factory, many customers see no improvements or even worse, mechanical failures due to these features. The Hypertech PowerStay puts an end to these modes on your vehicle once and for all so you can enjoy your vehicle as it should be.

IMPORTANT NOTE FOR GM VEHICLES WITH ACTIVE ONSTAR
GM OnStar cannot run the full diagnostics when the PowerStay or similar devices are plugged into the OBD-II port of the vehicle. PowerStay users that have the OnStar diagnostic app on their phone will get a message saying that some modules have faults, which is not accurate.
IMPORTANT NOTE FOR VEHICLES THAT ARE NOT DRIVEN FOR EXTENDED PERIODS OF TIME
The PowerStay consumes around twenty milliamps of current when the vehicle is running and goes into sleep mode when the vehicle is shut off and draws two milliamps when in sleep mode. The sleep current draw is minimal compared to the vehicles own current draw, but customers should be advised to disconnect the PowerStay from the vehicle if the vehicle is in long term storage or not driven for an extended period of time.
The Hypertech PowerStay offer a very simple installation. Just plug the PowerStay into the OBD-II diagnostic port under the driver's side dash, then just drive your vehicle... That's all there is to it!
Re-enable either feature by first turning your vehicle off then unplugging the PowerStay from the OBD-II diagnostic port under the driver's side dash.

Hypertech's liability under this warranty shall be limited to the prompt correction or replacement of any defective part of the product which Hypertech determines to be necessary.

Return Your Vehicle To Stock Tuning
BEFORE Taking Your Vehicle In For Service
If you take your vehicle to a dealer or mechanic for service, you must first remove the Hypertech Power Tuning and restore the stock programming. This is because diagnostic devices expect to find stock calibrations and will often overwrite the program if the latest stock calibration is not found in the computer's memory. This will result in the loss of your Hypertech Power Tuning data. The Power Tuning can be easily removed to restore the stock tuning before you take your vehicle in for service, enabling the service technician to upgrade your stock calibrations. After the service is complete, you can reinstall your Hypertech Power Tuning. If you have any questions related to service issues, please call Hypertech at 901.382.8888.
