The wait is over.

N2 Speed is now offering custom HP Tuners calibration support for the 2023–2025 Corvette Z06 and ZR1 platforms. This marks a major breakthrough in unlocking the next generation of GM’s most advanced performance architecture.

For serious builders, track drivers, and forced-induction enthusiasts — this is where the real performance begins.

2023–2025 Corvette Z06 (LT6 – 5.5L Flat-Plane Crank)

Chevrolet Corvette Z06

The C8 Z06 introduced the LT6 5.5L flat-plane crank V8, one of the most sophisticated naturally aspirated engines GM has ever produced:

• 670 HP factory rating

• 8,600 RPM redline

• Dual overhead cam architecture

• Advanced torque modeling

• New-generation GM Global B electrical architecture

From a calibration standpoint, this platform is dramatically more complex than previous Corvette generations. Torque management, airflow modeling, and driver demand mapping are tightly integrated with chassis control systems.

With HP Tuners support now available, we can properly recalibrate:

• Throttle mapping & driver demand

• Torque model & predicted torque tables

• Fueling strategies (DI optimization)

• Cam timing control

• Rev limit adjustments

• Speed limiter removal

• E85 / flex fuel scaling (where applicable)

• Bolt-on airflow recalibration

• Track-focused drivability refinement

2025 Corvette ZR1 (Twin Turbo LT7 Platform)

Chevrolet Corvette ZR1

The 2025 ZR1 raises the bar even further with a factory twin-turbocharged platform (LT7). This moves Corvette tuning into a new tier of airflow and boost management complexity.

Key calibration control areas include:

• Boost control strategy optimization

• Wastegate mapping

• Torque intervention reduction

• Fuel system scaling for higher airflow

• Knock strategy refinement

• Thermal management optimization

• Transmission torque management coordination

This is not a “flash and go” platform. It requires a deep understanding of GM’s torque-based control structure — something N2 Speed specializes in.

ECU & Security Architecture

Both platforms operate on GM’s latest encrypted controller architecture. Unlock procedures and calibration workflow require:

• Proper HP Tuners interface hardware

• Controller licensing

• Bench unlock procedures (if required)

• Correct OS recognition and calibration strategy

We are seeing these vehicles operate on newer GM controller families derived from the E99 architecture, but with updated security layers.

HP Tuners Support Is Key

Without full HP Tuners definition support, proper torque modeling edits and airflow calibration simply are not possible.

Now that definition support is active, serious tuning can begin.

What This Means for Z06 & ZR1 Owners

This unlocks real capability for:

Bolt-On Builds

• Headers

• High-flow exhaust systems

• Intake modifications

• Flex fuel conversions

Track Builds

• Refined throttle sensitivity

• Torque smoothing under corner exit

• Rev matching optimization

• Launch & traction refinement

Forced Induction & High Power Builds

• Boost scaling

• Fuel system recalibration

• Injector characterization

• High-RPM airflow modeling

Why This Platform Requires an Experienced Calibrator

The C8 Z06 and ZR1 are fully torque-model dependent. Unlike older LS/LT platforms, you cannot simply modify spark and fueling tables.

You must correctly calibrate:

• Virtual torque tables

• Airflow coefficients

• Driver demand limits

• Predicted torque

• Inverse torque mapping

• Transmission torque limits

• ETC modeling

Improper edits will trigger:

• Torque intervention

• Throttle closure

• Power reduction

• Inconsistent track performance

• DTC activation

This is not an entry-level tuning platform.

N2 Speed Calibration Approach

Our workflow includes:

1. Data logging with HP Tuners VCM Scanner

2. Airflow model verification

3. Torque model validation

4. Controlled dyno or track refinement

5. Iterative calibration adjustments

6. Final drivability validation

We build calibrations for:

• Street performance

• Road course

• Drag racing

• High horsepower builds

The Bottom Line

The 2023–2025 Corvette Z06 and ZR1 platforms represent the most advanced production Corvettes ever built.

With HP Tuners support now active, true performance calibration is finally possible.

If you're serious about extracting safe, repeatable power from your C8 Z06 or ZR1 — this is where precision calibration makes the difference.
