The 034Motorsport Dynamic+ Tuning Software for 8J Audi TTRS equipped with the EA855 2.5T inline-five engine is designed to transform the driving experience of your vehicle! Flashed directly through your vehicle’s OBD-II port, 034Motorsport’s proprietary calibrations for the ECU safely and effectively increase the power output of the turbocharged inline-four in a refined manner. The result is a significant improvement in acceleration and throttle response, without any sacrifice in driveability or reliability.
034Motorsport 8J Audi TTRS EA855 2.5T Dynamic+ Performance Software was developed entirely in-house on 034Motorsport's Development 8J Audi TTRS. The calibrations were then refined on multiple enthusiast-owned beta tester cars around the world.
034Motorsport Engineers develop special inhouse tools that allow us to access the firmware and maps inside the factory ECU, this level of engineering is required to prevent work-arounds and bandaids that many aftermarket companies resort to. 034Motorsport engineers and optimizes the ECU calibrations just like Volkswagen engineers would, but accessing the source of how the ECU controls the engine and making changes at the base level.
This is the ONLY way 034Motorsport can ensure our calibrations meet our high standards for ultimate power with smooth drivability, perfect function, reliability and added functions and features even beyond what the factory programming can provide.
All Dynamic+ tunes can now be flashed anywhere you please with the 034SPI (Smartphone Interface) Mobile Flashing application! Designed for use on iOS and Android Devices as well as Apple Silicon-equipped laptops (M1, M2, M3), 034SPI allows you to easily flash your car, change fuel maps, configure live data displays, record and submit data logs to 034Motorsport's Tuning Support team, and utilize diagnostic support tools such as DTC/CEL code read/clear and more!

Notes Regarding Crackle Overrun
Please read before ordering. Eurosport Performance does not carry live inventory on this site. Most products are ordered for you directly from the manufacturer or our suppliers, and we follow their lead times. Placing an order confirms you have read and accepted the availability terms below.
| In stock
Ships within 24 to 48 hours
Products marked in stock are on our shelves in Montreal and leave within one to two business days.
|
Ordered for you
Most orders ship in 5 to 7 business days
Everything else is ordered from the manufacturer or supplier when you order. Delays can occur; if they do, we contact you.
|
|
Supplier lead times apply
If a product is not listed as in stock here and is on backorder at the manufacturer, it will most likely be on backorder for us too. We will tell you as soon as we know.
|
We keep you informed
You receive a confirmation when the order is placed, a notice if a delay comes up, and tracking the moment it ships.
|
Only products explicitly marked in stock are on our shelves. For everything else, the fastest way to know the current lead time is to ask us before you order; we check with the supplier and reply with a date.
Confirmed means we have placed the order with the manufacturer or supplier on your behalf. Shipping follows once the part reaches us or ships directly to you, usually within 5 to 7 business days for products that are available at the source.
We tell you as soon as the supplier confirms it, with the expected date when they give one. You can keep the order open, switch to an alternative we suggest, or cancel for a full refund before the part ships.
Yes. Any order that has not shipped can be cancelled by contacting us, and the refund goes back to your original payment method. Please contact us rather than opening a dispute with your bank: a cancellation takes us minutes, a chargeback takes weeks and freezes the refund in the meantime.
Sometimes. Larger or special-order items can ship to you directly from the supplier to save days in transit. You still receive tracking from us either way.
Orders ship from Montreal or directly from our suppliers. For Canadian addresses the price you pay is the price, with no import or duty fees added on delivery. See our shipping policy for details.
You get an email with the tracking number the moment the label is created, and you can follow the order in your account on the site or in the SPECD app.
Want a lead time before you order? Email us or use the contact page with the product name and your vehicle, and we will confirm availability with the supplier.
Products are warrantied by their manufacturer. Eurosport Performance is an authorized reseller: every part we sell is covered by the manufacturer's own warranty, with its own terms and duration. Claims go through us, so you deal with Eurosport Performance rather than a form on the brand's site, but whether a claim is accepted is the manufacturer's decision.
|
Manufacturer terms apply
Duration and coverage are set by the brand and differ from one to the next: some cover one year, some a lifetime, some only the original purchaser. The brand's warranty page is the reference; ask us if you cannot find it.
|
We file the claim for you
Contact us with your order number, photos and a description of the issue. We open the claim with the manufacturer, follow it up, and arrange the repair, replacement or credit they approve. The manufacturer decides whether the claim is accepted.
|
|
Fitment guarantee: North America only
We guarantee fitment for vehicles sold in the North American market. Vehicles from other markets are out of scope; specifications differ, and it is the customer's responsibility to confirm compatibility before ordering.
|
No warranty on tuning files
ECU and TCU tunes and other software files are sold without warranty and are not returnable once delivered or flashed. Tuning can affect your vehicle's factory warranty; please read the brand's terms before purchasing.
|
|
Proof of purchase
Your Eurosport Performance order is the proof of purchase every manufacturer asks for. Keep the order confirmation; it is also in your account on the site and in the SPECD app.
|
What is usually not covered
Damage from improper installation, modification, abuse, racing or an incorrect application for the vehicle, and normal wear items such as pads, clutch discs and filters. Shipping and labour are covered only when the manufacturer's terms say so.
|
It is the manufacturer's warranty for that product. Where the brand publishes it, we note it in the description; otherwise contact us before ordering and we will confirm the exact terms with them.
Stop using it if it is a safety-related part, then contact us with your order number, clear photos, and when and how the issue appeared. Do not return anything until we confirm the claim; manufacturers often require an inspection or an authorization number first.
The manufacturer. We prepare and submit the claim, provide the proof of purchase and push for a fair outcome, but acceptance, replacement or credit is their call under their terms. We pass their decision on to you as soon as we have it.
It depends on the manufacturer. Simple cases are approved in days; claims that need the part inspected can take a few weeks. We keep you updated at each step and push when it drags.
No. Tuning files are software; once delivered or flashed they cannot be returned, and they carry no warranty from Eurosport Performance or, in most cases, from the tuner. Support for the tune itself (revisions, flashing questions) comes from the tuning brand under its own terms.
No. Our fitment guarantee covers vehicles sold in the North American market only. European, Japanese and other market vehicles can differ in engines, electronics and dimensions, and a part listed for the North American model is not guaranteed to fit. If you order for one of these vehicles, confirming compatibility is your responsibility, and fitment issues on such vehicles are not covered by returns or warranty.
Labour is not covered unless the manufacturer's terms specifically include it. Having the part installed by a qualified shop protects your claim: improper installation is the most common reason a manufacturer declines.
No. Returns cover unused parts you no longer want, under our refund policy. Warranty covers a part that fails in use, under the manufacturer's terms. If you are unsure which applies, contact us and we will point you to the right one; please do not open a bank dispute, as it pauses both processes.
Questions about coverage before you buy? Email us with the product and your vehicle and we will confirm the manufacturer's terms.
