CTZ Flasher Remote Tuning Service (1999–2024 GM Vehicles)

Unlock the true potential of your GM vehicle with our CTZ Flasher Remote Tuning Service. Whether you drive a Camaro, Corvette, Silverado, Sierra, Tahoe, or other GM model, we make tuning simple and convenient. No shipping your ECU, no downtime — we send you our flasher and walk you through the process step by step.

How it works:

• We ship you our CTZ Flasher device

• You’ll need a laptop (or phone for supported models)

• We guide you remotely through the entire process from start to finish

• Use the flasher to download and install your custom tune directly to your car

Features of the CTZ Flasher:

• Store and switch between multiple tunes directly from your phone

• Read and clear DTCs (diagnostic trouble codes)

• Data logging to monitor performance and refine adjustments

• Portable, simple, and user-friendly

Purchase or Borrow Options:

• Borrow the Flasher → Included with the standard service price (use the return label to send it back after tuning)

• Buy the Flasher → Keep it for future tuning, diagnostics, and data logging (+$400 upgrade fee)

• If you borrow the flasher but don’t return it, you’ll be charged the purchase fee.

Custom Add-Ons Available:
Choose from a variety of performance options — Pops & Bangs, Launch Control, Rev Limiter Adjustments, Ghost Cam, Fuel Economy Tunes, and more — all tailored to your setup.

Important Note:
Some GM vehicles (especially newer models) may require additional licensing or ECU unlock services before tuning. We’ll advise you of any extra steps needed when you provide your vehicle details.

Upgrade your GM with confidence and enjoy the freedom to switch tunes, log data, and take full control of your performance with the CTZ Flasher Method.

Would you like me to also draft a side-by-side comparison block (GM vs Dodge service) so customers on your site instantly see that you cover both markets? That could help conversions.
