Corvette Custom Tuning — C5, C6, C7 & C8 Remote Tunes
N2 Speed builds custom Corvette tunes for every LS and LT generation, from the 1997 C5 LS1 to the mid-engine C8 Stingray, Z06 and ZR1. Every calibration is written around your exact modification list, fuel and driving goals, then refined from your data logs — we do not resell generic canned maps.
We tune the Corvette on HP Tuners (MPVI2, MPVI3 and MPVI4 interfaces, plus RTD real-time tuning devices) and DiabloSport (inTune i3 and Trinity 2). Fueling, spark advance, cam phasing on LT engines, throttle response, AFM/DoD behavior, rev and speed limiters, shift points and torque management are all addressed, and revisions are included until the car runs the way you want.
Corvette Factory Horsepower by Generation
Factory SAE-rated output for every Corvette engine we calibrate. These are the crank figures the car left the factory with — the tuning gains further down this page are measured at the wheels, so the two sets of numbers are not directly comparable.
| Years & Model | Engine | Factory Horsepower |
|---|---|---|
| 1997-2000 C5 Corvette | 5.7L LS1 V8 | 345-350 hp |
| 2001-2004 C5 Corvette | 5.7L LS1 V8 | 350 hp |
| 2001-2004 C5 Z06 | 5.7L LS6 V8 | 385-405 hp |

Corvette Tuning Stages and Pricing
| Stage | Built for | Typical gains | Price |
|---|---|---|---|
| Stage 1 — Stock & Bolt-Ons | Stock cars and builds with an intake, headers, exhaust or ported throttle body | 15-30 wheel hp on naturally aspirated cars, 30-60 wheel hp on factory-supercharged LS9, LT4 and LT5 cars, on 93 octane | $450 |
| Stage 2 — Heads, Cam & Stroker | Naturally aspirated builds with a camshaft, ported heads or a stroker | 50-120 wheel hp depending on the cam and cylinder head package | $550 |
| Stage 3 — Supercharged, Turbo & Nitrous | Forced-induction and nitrous builds, including pulley and blower upgrades on factory-supercharged cars | 100-300+ wheel hp depending on boost level and fuel | $650 |
Exact gains for your car are listed on each engine page above. The C8 Z06 is $750 and the C8 ZR1 is $750 for Stage 1 and $950 for Stage 3, reflecting the extra work on the LT6 and LT7. Automatic C6 and C7 cars can add a 6L80 transmission tune or an 8L90 transmission tune for shift points, firmness and torque management. Not sure which stage fits? Email your mod list to sales@n2speed.com or call (954) 406-8550.
What You Need Before You Order
- An HP Tuners interface — MPVI2, MPVI3 or MPVI4, or an RTD device — plus credits for your car. C8 Stingray needs an MPVI3 or MPVI4; C8 Z06 and ZR1 need an MPVI4. New hardware? Start with the HP Tuners MPVI4 with Pro Feature Set, or a DiabloSport i3 / Trinity 2
- A Windows laptop with HP Tuners VCM Suite installed
- Your stock read — we walk you through pulling it
- A wideband air/fuel gauge — recommended for Stage 2, required for Stage 3
How Remote Tuning Works
- Order your stage. Pick the engine page and package that matches your build.
- Send your information. Email your VIN, mod list, fuel type and stock read to sales@n2speed.com.
- Flash the file. We email your calibration, normally within 1-2 business days.
- Log and refine. Send data logs and we revise until the car is dialed in. Tuning is log-based — if you want faster revisions, we can coordinate a dyno appointment.
Corvette Modules, Unlocks and Bench Work
Chevrolet does not lock the C5, C6, C7 or C8 Stingray engine computer the way Stellantis locks 2015 and newer Dodge PCMs, so engine tuning on those cars is a straight OBD-II flash. Two exceptions: the 2017-2019 C7 8L90 T87A transmission module must be unlocked before transmission tuning, and the C8 Z06 and ZR1 E68 ECM must go through our GM E68 ECM unlock service before any calibration can be written. Both are handled through our GM ECM and TCM unlock & programming service. Send your VIN and we will confirm which route your car needs before you spend anything.
What Corvette Custom Tuning Delivers
- More wheel horsepower and torque — optimized fuel, spark and torque management tables
- Sharper throttle response — pedal and electronic throttle mapping refined for how you drive
- Transmission calibration — shift points, firmness and converter lock-up on 4L60E, 6L80 and 8L90 automatics
- Fuel-specific files — 91 octane, 93 octane or E85
- Rev limiter and speed limiter changes on request
- Forced-induction calibration — Procharger, Whipple, Magnuson, Edelbrock, turbo kits and pulley-upgraded LS9, LT4 and LT5 cars
Corvette Tuning FAQs
How much does a Corvette tune cost?
Our Corvette custom remote tunes are $450 for Stage 1, $550 for Stage 2 and $650 for Stage 3 on the C5, C6, C7 and C8 Stingray. The C8 Z06 tune is $750, and the C8 ZR1 is $750 for Stage 1 and $950 for Stage 3. Pricing includes revisions after we review your data logs.
How much horsepower does a stock Corvette make?
From the factory the C5 LS1 makes 345-350 hp and the C5 Z06 LS6 makes 385-405 hp. The C6 LS2 makes 400 hp, the LS3 430-436 hp, the Z06 LS7 505 hp and the ZR1 LS9 638 hp. The C7 Stingray LT1 makes 455-460 hp, the Z06 LT4 650 hp and the ZR1 LT5 755 hp. The C8 Stingray LT2 makes 490-495 hp, the C8 Z06 LT6 670 hp and the C8 ZR1 LT7 1,064 hp. These are SAE crank ratings.
How much horsepower will a tune add to a Corvette?
On 93 octane a Stage 1 calibration typically returns 15-30 wheel horsepower on a naturally aspirated Corvette and 30-60 wheel horsepower on a factory-supercharged LS9, LT4 or LT5 car. Cam, cylinder head and stroker builds see 50-120 wheel horsepower at Stage 2, and supercharged, turbocharged or nitrous builds see 100-300 wheel horsepower and up at Stage 3 depending on boost and fuel. Results depend on your modifications, fuel quality, altitude and ambient temperature.
Do I need to unlock my Corvette ECM before tuning?
Not on most cars. The C5, C6, C7 and C8 Stingray engine computers are not locked and flash through the OBD-II port. The C8 Z06 and C8 ZR1 use the E68 ECM, which must be unlocked through our GM E68 ECM unlock service first, and 2017-2019 C7 automatics need the T87A transmission module unlocked for transmission tuning.
Which HP Tuners interface do I need for a Corvette?
C5, C6 and C7 Corvettes can be tuned with an MPVI2, MPVI3 or MPVI4, or an RTD device. The C8 Stingray needs an MPVI3 or MPVI4, and the C8 Z06 and ZR1 need an MPVI4. Credits are purchased for your car on top of the interface.
Can you tune the automatic transmission too?
Yes. We calibrate shift points, shift firmness, torque management and converter behavior on the 4L60E, 6L80 and 8L90 automatics. On 2017-2019 C7 automatics the T87A module has to be unlocked first.
Do you support E85 and 91 octane?
Yes. We build 91 octane, 93 octane and E85 calibrations. Tell us which fuel you run when you send your mod list.
Do I have to bring my Corvette to your shop?
No. Corvette tuning is fully remote. You email your stock read, VIN and modification list, we send the calibration back for you to flash at home, then you send data logs and we revise until the car is where you want it. N2 Speed is in Pompano Beach, Florida, and local customers are welcome, but nothing about the process requires a visit.
Will a custom tune void my Corvette factory warranty?
A dealer can deny a powertrain warranty claim if they find a modified calibration, and that applies to any aftermarket tune, not just ours. If your Corvette is still under factory warranty, factor that in before ordering.
