The Boost Tee is a pneumatic bleed valve that allows an increase in boost on turbocharger systems where boost-based actuators are used and are suitable for internal and external wastegate systems. By manipulating the reference signal to an internal wastegate actuator or external wastegate, an increase in boost over and above the base spring pressure can be achieved. It is common to reach 100 - 200% increases in boost over the base spring pressure.
Using our proven detent system, the controller can increase the boost in defined steps, and the locking mechanism allows the boost level to be set & secure from tampering.

FAQ
What’s the first rule of boost control?
Ensure you have an over-boost cut-out. This safety feature is built into all factory, aftermarket & programmable ECUs. Make sure it is set at a sensible & reasonable limit. Increasing the boost will put more load on your engine, and there is another tune-related factory you must always consider. If in any doubt, speak with a professional tuner/calibrator.
Can I use this on any turbocharged engine?
If your engine is turbocharged and uses a boost-based actuator for wastegate flap style control, then yes. This Boost Controller will work on boost-based internal wastegate actuators and external wastegates. It will not work for VGT (Variable Geometry) Turbochargers, also known as VVT (Variable Vein) and VNT (Variable Nozzle) Turbochargers.
How much boost can I add?
This will come down to the rest of your setup & tune. If in any doubt, we recommend you contact a professional tuner or workshop for advice here.
What is Gate Feature?
Gate Feature is a unique Turbosmart feature that ensures our boost controllers can give you the best possible response. Turbosmart’s Boost Controllers can provide the most aggressive boost curve by manipulating the pressure signal into your actuator.
Can the ’Gate Feature’ be disabled?
Yes. Looking at the technical drawings available online, you will see the ’Gate Ball’ and ’Gate Spring’ behind the inlet nipple. Removing the nipple and re-assembling the Boost-Tee without the Gate Ball & Spring will provide you with the same type of control you expect from Turbosmart without the gate feature enabled.
Is the arrow important?
Yes. If you’re having issues with boost control, please take a minute and check your connection method and ensure the hoses are routed correctly – Take note of the arrow on the boost-Tee.
Can I turn my boost down?
Using a correctly installed Turbosmart Boost-Tee, you can adjust boost from around your base mechanical spring pressure (in your wastegate or actuator) up to usually around 2-3 times the base pressure. However, you cannot use these devices to turn the boost down lower than the base spring pressure.
Is one click one PSI?
No! Either way, one click is relative to your engine and turbo. The more efficient it is, the fewer clicks you need to achieve more boost. However, as the boost rises, efficiency decreases. This means you’ll need to work harder (more clicks) for more boosts at higher levels.
Availability & Shipping
Standard Shipping applies to every order — rates are calculated at checkout, with tracking provided once your order ships. Track your order any time at eurospeed.co/pages/track for a live delivery estimate. International delivery is available at checkout, with rates calculated for your location.
Delivery time depends on the product. Most in-stock parts ship within days, while carbon fiber and made-to-order items may require production time before they ship. For the specific timeline on any item, check the Availability & Shipping section on that product’s own page — the guide below covers our general shipping types.
Shipping Overview
Depending on the item, free air freight may be available for select carbon fiber components, with estimated shipping around 1–2 weeks after dispatch. Larger hoods, oversized body components, and certain made-to-order items may require sea freight and longer delivery windows. If timing is important, please contact us at support@eurospeed.co before placing your order.
Shipping Coverage
EuroSpeed ships to customers across the United States and internationally. Shipping is included in the price of eligible products for your convenience and covers the initial cost of delivery to your destination.
Import duties, taxes, clearance fees, or customs charges required by your destination country are not included and remain the recipient’s responsibility.
Order Processing & Fulfillment
Every order is reviewed, processed, and prepared before shipment. Most in-stock products are processed within 1–3 business days, though some orders may take up to 5 business days depending on fulfillment location, product type, order volume, or courier pickup timing.
EuroSpeed stocks select high-demand products at our U.S. facility and international fulfillment centers. Because our catalog includes many vehicle-specific and specialty parts, not every product is held in-house at all times.
Some orders may ship through our trusted fulfillment network, which may include verified manufacturing partners, authorized distributors, regional warehouses, and international fulfillment centers.
- Orders may ship from a U.S. warehouse, international warehouse, manufacturer, or authorized fulfillment partner.
- Some products may require additional handling, processing, production, or quality-check time before shipment.
- Orders enter fulfillment shortly after being placed and may no longer be eligible for cancellation once processing, production, or shipment preparation begins.
Custom, Made-To-Order & Oversized Items
Custom, made-to-order, and oversized product categories may include carbon fiber steering wheels, hoods, trunk lids, fenders, front lips, splitters, side skirts, diffusers, bumpers, body kits, widebody components, select spoilers, rear wings, and other large carbon fiber components.
Many carbon fiber items are made to order. Some products may already be stocked and ready to dispatch when available, but if inventory is unavailable, your purchase reserves the next available production slot instead of waiting for a separate restock listing.
Production time: Production can take 1–4 weeks depending on product type, selected options, finish, current queue, and quality-control timing.
Shipping time: Shipping can take 2–10 weeks depending on item size, freight method, destination, customs processing, carrier delays, warehouse transfers, and final delivery location. Carbon fiber steering wheels typically ship faster, with shipping usually taking 3–7 business days after dispatch.
By purchasing custom, made-to-order, or oversized items, you acknowledge and accept the extended production, fulfillment, and shipping timelines associated with these products.
Tracking Updates & Delays
All orders receive a tracking number once generated by the courier. Tracking may take 2–3 business days after dispatch to show movement in the courier’s system.
Certain international, oversized, or freight shipments may show limited updates during transfer between fulfillment locations, warehouses, customs, or final-mile carriers. In some cases, tracking is provided or begins updating once the item reaches a regional warehouse, local carrier, or final delivery network.
Shipping timelines are estimates and are not guaranteed. Delays caused by high order volume, weather conditions, customs inspections, carrier disruptions, production queues, warehouse transfers, holidays, or other external factors may occur and are outside of EuroSpeed’s direct control. These delays do not qualify for cancellations or refunds unless the carrier officially marks the package as lost.
Delivery Responsibility
Upon delivery, carefully inspect the item for visible defects or damage before signing for it. If the item is damaged or not as expected, do not accept the package. Once a damaged or defective product is accepted, EuroSpeed cannot cover return shipping costs.
EuroSpeed is not liable for packages marked as delivered by the carrier. If a package is lost, stolen, or missing after being marked as delivered, the customer must file a claim directly with the shipping carrier. Our team will assist with available documentation when needed.
Shipping addresses typically cannot be changed once an order has been marked as shipped. If an address change is possible through the carrier, any carrier redirect, correction, or address-change fee will be the customer’s responsibility.
Please ensure your shipping address is entered correctly at checkout. Orders shipped to incorrectly provided addresses are the customer’s responsibility. EuroSpeed is not responsible for failed deliveries, additional shipping costs, lost packages, or refunds caused by incorrect shipping information, failure to accept delivery, or failure to collect a package from the post office or carrier pickup location within the required time frame.
