Bundle: UpMap + Intake Velocity Stacks Kit by GRT for Aprilia Tuono V4 E5+ EU 2025 (USA 2026)
SKU: MB00322-GRT-VSTACKS-UPMAP
UpMap T800+ & GRT Velocity Stacks Bundle for Aprilia Tuono V4 E5+ 2025 / USA 2026
Upgrade the intake performance and ECU calibration of your Aprilia Tuono V4 E5+ with this combined UpMap T800+ and Gabro Racing Team Velocity Stacks package. Bringing together two complementary upgrades in one bundle, the kit improves the way air is delivered into the engine while providing direct access to the dedicated Gabro Racing ECU calibration developed to work with the modified intake.
Designed specifically for the latest-generation Tuono V4, this package combines precision-engineered GRT intake stacks with the UpMap T800+ Bluetooth ECU programming device, providing a straightforward route to improved airflow, smoother power delivery and stronger performance through the mid and upper rev range.
Gabro Racing Team Velocity Stacks
The standard intake funnels are replaced by a set of specially developed Gabro Racing Team velocity stacks, designed to optimise the airflow entering the Tuono V4's cylinders.
Rather than simply chasing peak horsepower, their geometry has been developed to improve the shape of the power curve, helping to reduce dips and flat spots while producing a smoother, more progressive delivery. Gabro Racing quotes an increase of approximately 2–3 hp through the mid and upper RPM range when used with the appropriate ECU calibration.
The stacks are manufactured using precision 3D printing in lightweight and durable PA12 material. They install directly into the standard airbox with no cutting or permanent modification required.
UpMap T800+ ECU Management
Included in the bundle is the UpMap T800+, allowing the Tuono's original ECU to be programmed directly from a compatible iOS or Android smartphone.
Connecting to the motorcycle through the supplied OBD cable and communicating with the UpMap app via Bluetooth, the T800+ provides access to Gabro Racing Team's extensive library of Tuono V4 ECU calibrations. The original ECU map can be retained for restoration to the standard calibration when required.
The UpMap system also provides useful diagnostic functionality, including live engine data and the ability to read and clear ECU errors. At the end of the flashing procedure, throttle learning and error reset procedures are performed automatically.
Dedicated STACKS ECU Map Included
The GRT Velocity Stacks include a promotional coupon worth €168 for the dedicated Gabro Racing STACKS ECU map through the UpMap Store. With the T800+ included in this bundle, you have the hardware required to redeem, download and install the appropriate calibration onto the motorcycle's standard ECU.
The UpMap package also includes the standard GRTMAP entitlement, providing access to an additional compatible Gabro Racing Team map where applicable.
Why Buy the Bundle?
Velocity stacks and ECU calibration work most effectively as a matched system. Changing the physical characteristics of the intake alters the way the engine breathes, while the dedicated Gabro Racing calibration allows the ECU setup to be matched to the revised intake configuration.
This bundle therefore provides both sides of the upgrade in one package: the GRT hardware to improve intake airflow and the UpMap system required to install and manage the corresponding ECU calibration.
