The Chevy Hhr Ss, a sporty and versatile vehicle, holds even more potential under the hood. For owners looking to elevate their driving experience, a Stage 1 tune offers a significant performance boost. This upgrade optimizes your HHR SS’s engine control unit (ECU) to unlock hidden horsepower and torque, transforming your daily drive into a more exhilarating experience. Let’s delve into the specifics of what a Stage 1 tune can do for both manual and automatic Chevy HHR SS models.
Stage 1 Tune for Manual Transmission Chevy HHR SS
The manual transmission HHR SS models are known for their robust drivetrain, capable of handling substantial power. Especially if your vehicle is equipped with the G85 Limited Slip Differential, you’ll experience enhanced traction and reduced torque steer when you unleash more power.
From the factory, a manual HHR SS typically outputs around 260 horsepower and 260 lb-ft of torque. However, dyno tests often reveal that these figures are somewhat underrated, with real-world wheel horsepower reaching approximately 240 and wheel torque around 250 lb-ft.

Our Stage 1 tune is engineered to extract even more from your manual HHR SS. Expect to see gains taking you to an impressive 290 to 310 wheel horsepower and a robust 340 to 370 lb-ft of wheel torque, depending on any existing aftermarket modifications you may have. This translates to a peak increase of 50 to 70 wheel horsepower and a substantial 90 to 120 lb-ft of wheel torque over the stock configuration. This power surge will result in significantly improved acceleration, throttle response, and overall driving dynamics.
Stage 1 Tune for Automatic Transmission Chevy HHR SS
While the automatic transmission HHR SS models offer convenience, they are factory-tuned with a more conservative power output due to the limitations of the 4-speed automatic transmission’s torque handling capacity. General Motors released these models with slightly less horsepower and torque compared to their manual counterparts. Our Stage 1 tuning for automatic HHR SS vehicles is specifically developed with powertrain safety as a paramount concern.
Stock automatic HHR SS models generally produce around 220 horsepower. Our Stage 1 tune effectively elevates this to approximately 280 horsepower. While this is just slightly shy of the peak horsepower achievable with manual models, we strategically limit the torque output for automatic tunes to around 300-310 lb-ft. This torque management ensures the longevity and reliability of your automatic transmission while still providing a significant performance improvement.

Beyond engine tuning, our automatic HHR SS Stage 1 tune also includes transmission enhancements. We recalibrate the transmission tables to achieve quicker shift times, reducing shift duration by approximately 0.25 seconds per shift. Furthermore, we increase shift pressure to minimize torque converter slippage during high RPM shifts. These transmission optimizations contribute to enhanced acceleration and a more responsive driving experience, independent of the engine power gains. This added transmission tuning comes at no extra cost and further amplifies the benefits of the Stage 1 upgrade for your automatic Chevy HHR SS.
Conclusion
A Stage 1 tune for your Chevy HHR SS is a transformative upgrade, regardless of whether you have a manual or automatic transmission. Experience a significant surge in horsepower and torque, leading to enhanced acceleration, improved throttle response, and a more engaging driving experience. Unlock the true potential of your Chevy HHR SS with a Stage 1 tune and enjoy the exhilarating performance that awaits.
