Griffin Motorsports - Stage.I Remote Tuning Package featuring the HP Tuners MPVI4 Interface.
By now it should be clear just how incredibly capable our modern engines are from factory. Despite all of their advancement in Di fueling, more forged components, and factory supercharging, the OEM’s have still left so much on the table for savvy minds at HP tuners to help you extract. No matter the platform, it never seems to take long before the Griffin Motorsports KONG Ported Blower Package, E85 Sensor Kit, Upgraded XDI Fuel Injectors, Head & Cam Packages and cooling mods are all in your shopping cart, just waiting to pull the trigger. And when that branded box of sexy parts arrives, you are quickly reminded that the only way you can extract the power you want, and provide the durability you need, is with master level calibration.
Unfortunately, the amount of master tuners for the LS/LT engine platform are few and far between which means if you are like me, you have been and or will continue to utilize a remote tuner in order to get the most from your build, and keep things safe. No better way to kick off that tuning process than with one of our Griffin Motorsports staged remote tuning hardware packages.
HP Tuners MPIV4.
The HP Tuners MPVI4 is the industry-standard vehicle interface that unlocks full access to your ECU and TCM, allowing you to flash custom calibrations, log high-resolution data, and safely optimize your LS/LT/Global B platform—whether you’re tuning the car yourself or working with a professional remote tuner like Justin White Tuned.
The MPVI4 is a high-speed vehicle interface (VCI) that connects your car to HP Tuners VCM Suite, giving you:
Full ECU and TCM read/write capability
High-speed data logging with expanded channel access
Support for custom tuning files created by you or your tuner
Compatibility with gasoline, E85, flex-fuel, boosted, and NA LT setups
If you’re modifying your engine, this isn’t optional—it’s foundational.
Designed for Remote Tuning:
If you’re working with a professional tuner, MPVI4 is the required communication bridge:
Read and flash tune files your tuner sends you
Log high-resolution data exactly how they request
Email logs and revisions back and forth with confidence
Make changes on your schedule—no shop visits required
Allows you to work with ANY TUNER in the world (no more restrictions)
Allows you to make small tune changes on the fly for those with experience
Why MPVI4 Is a Major Upgrade Over Previous Generations:
Compared to earlier MPVI interfaces, the MPVI4 delivers:
Improved USB-C connectivity
32X More RAM Memory (32 vs 1024)
Faster processing and improved stability
WiFi Enabled with speeds up to 150mbps
Utilizes the improvements on Bluetooth 5.2
Support for the latest GM operating systems
Expanded logging bandwidth for modern ECUs
Multi-colored status lights for better visual communication
3X More processing power (single core 500mHz vs. dual core 1.7GHz)
More efficient handling of complex LT torque models and flex-fuel data
When you’re logging ethanol content, fuel pressure, airflow models, and torque intervention all at once, speed and reliability matter. This level of access is why HP Tuners remains the gold standard for GM performance tuning.
How do HP Tuners Credits actually work?
HP Tuners uses a credit-based licensing system that allows you to unlock (license) specific vehicle control modules before making calibration changes. Credits are purchased digitally and stored in your HP Tuners account. When you connect your MPVI interface to a vehicle and license it, the required number of credits is deducted and permanently tied to that vehicle’s modules (ECM, TCM, etc.). Once licensed, you can read, modify, and flash that vehicle as many times as you want—there are no recurring fees, subscriptions, or limits on reflashes for that vehicle. Credits are vehicle-specific, not tune-specific, meaning future modifications don’t require additional credits unless new modules are added.
Key Benefits of the HP Tuners Credit System
One-Time Cost per Vehicle – License once, tune forever; no annual fees or pay-per-flash models
Permanent Vehicle Licensing – Credits are locked to the VIN/modules, not individual tunes
Flexible & Scalable – Ideal for DIY enthusiasts, shops, and multi-vehicle owners
Mod-Friendly – Add cams, blowers, injectors, E85, or turbos without buying new licenses
Remote-Tuner Ready – Works seamlessly with professional remote tuners
Transparent Pricing – You know exactly what you’re paying for up front
