Description
Chevrolet Camaro 5.7L LS1 HP Tuners Stage 3 Custom Remote Tune — Supercharged, Turbo & Nitrous
A fully custom HP Tuners calibration for your Chevrolet Camaro 5.7L LS1 5.7L LS1 V8, written by N2 Speed for complete builds with a supercharger or turbo kit, including a dedicated nitrous map. 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 3 Tune Is For
Stage 3 suits complete builds with a supercharger or turbo kit, including a dedicated nitrous map. 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: 120-250+ hp depending on blower or turbo choice, boost level and fuel. 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
- Ls1 spark and fuel tables, maf and speed-density blending, idle and closed-loop behaviour, fan and cooling thresholds, rev limiter and 4l60e shift points and firmness
- 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
- A dedicated nitrous map on request, built for your shot size and fuel
Vehicle Fitment
1998-2002 Chevrolet Camaro Z28 and SS 5.7L LS1 (4th gen F-body). 4th gen LS1 cars flash straight through the OBD-II port — no unlock service and no bench work required.
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 — 1998-2002: 2 Universal Credits
Manual transmission? There is no transmission control module to calibrate, so choose Engine Only and select not applicable under Transmission Tuning.
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 — required for this stage
What's Included
- One custom calibration built for your 5.7L LS1 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 Camaro ECM is not locked, so engine tuning is a straight OBD-II flash. 2017 and newer 8-speed and 10-speed T87A transmission modules do need our GM ECM and TCM unlock & programming service first, and we offer GM PCM bench tuning service for modules that will not communicate. Send your VIN to sales@n2speed.com and we will confirm before you buy.
