Description
Chevrolet Corvette C7 ZR1 6.2L LT5 HP Tuners Stage 1 Custom Remote Tune — Stock & Bolt-Ons
A fully custom HP Tuners calibration for your Chevrolet Corvette C7 ZR1 6.2L LT5 supercharged 6.2L LT5 V8, written by N2 Speed for stock supercharged or turbocharged cars and builds with minor bolt-ons — exhaust, headers, intake or a ported throttle body. This is not a canned file: we build the calibration around your VIN, your modification list and the fuel you actually run, then refine it from your data logs.
Who This Stage 1 Tune Is For
Stage 1 suits stock supercharged or turbocharged cars and builds with minor bolt-ons — exhaust, headers, intake or a ported throttle body. If your build sits between two stages, email your mod list to sales@n2speed.com before ordering and we will tell you which package to buy.
Expected Gains
Typical results: 40-60 hp on 93 octane with the factory blower and pulley. Gains vary with modifications, fuel quality, altitude and ambient temperature. We calibrate for reliable, repeatable power — not a dyno number you cannot drive.
What We Tune
- Supercharger boost targets across both the port and direct injection systems, knock control, intake air temperature management, torque limits, launch control and 8l90 shift calibration
- Wide-open-throttle and part-throttle fueling
- Ignition timing with knock-safe margins for your fuel
- MAF and volumetric efficiency tables corrected for your airflow
- Throttle mapping and torque management limits
- Transmission shift points, firmness and torque limiting on automatic cars
- Optional speed limiter removal, fan thresholds and drive mode tweaks
Vehicle Fitment
2019 Chevrolet Corvette ZR1 supercharged 6.2L LT5 (7-speed manual or 8L90 automatic). The 2019 ZR1 uses the E99 controller, which requires HP Tuners' PCM upgrade service before it can be tuned. We handle that step for you — send your VIN first.
HP Tuners Credits This Vehicle Needs
Total Credits Needed
Credits are how HP Tuners licenses each vehicle. They load onto your MPVI4 and are spent once, the first time the module is read. Adding transmission tuning means a second module is licensed, so the credit total goes up — the options above already include both.
- Engine Only — 2019 LT5 - E99 PCM upgrade required: 8 Universal Credits
- Engine and Transmission — 2019 8L90 automatic: 12 Universal Credits
Manual transmission? There is no transmission control module to calibrate, so choose Engine Only and select not applicable under Transmission Tuning.
2017 and newer automatics: the 8-speed and 10-speed T87A transmission module is locked from the factory and must go through the GM ECM and TCM unlock & programming service before it can be written. We handle that for you.
The 2019 ZR1 also uses an S53 fuel injector control module, licensed separately at 3 credits if the port injectors need calibration.
Credit requirements are set by HP Tuners and can change with model year. If your car is not listed exactly, send your VIN to sales@n2speed.com and we will confirm before you buy anything.
What You Need
- HP Tuners MPVI4 with Pro Feature Set or another HP Tuners interface, plus credits for your vehicle
- Windows laptop with HP Tuners VCM Suite installed
- Ability to record and send data logs
- Wideband air/fuel gauge — recommended for this stage
What's Included
- One custom calibration built for your supercharged 6.2L LT5 V8 and modification list
- Revisions after log review until the vehicle is running correctly
- Direct email support with the tuner who wrote your file
- Turnaround: first file normally within 1-2 business days
Revision turnaround: Revisions are done in the order they are received during business hours. Set time frames are available with notice. After-hours and weekend revisions are done when available.
Locked Modules?
The 2019 ZR1 runs the E99 controller, which requires HP Tuners' PCM upgrade service before it can be tuned — we handle that step for you. The 8L90 transmission module also needs our GM ECM and TCM unlock & programming service before it can be written. For modules that will not communicate we offer GM PCM bench tuning service. Send your VIN and we will confirm the route before you spend anything.
