Integrated Engineering - IE Audi 3.0T Supercharged ECU Tune (B8/B8.5 S4 S5, C7 A6 A7, Q5 SQ5)
Unlock the true potential of your Audi 3.0T supercharged engine with Integrated Engineering's ECU Tune — the most comprehensive, street-to-track tuning solution available for the B8/B8.5 S4, S5, C7 A6, A7, Q5, and SQ5. Calibrated on Audi's factory Bosch ECU, this plug-and-play tune delivers massive power gains across all RPM ranges, improves throttle response, and removes the factory speed limiter — all with no hardware modifications required at the Core level. With over 5,000 cars tuned and a proven motorsport pedigree, iE tunes are trusted by enthusiasts and track-day drivers worldwide.
The iE tune is delivered and managed through the POWERlink Mobile app (iOS & Android), giving you full control to switch octane maps, upgrade tune packages, drain fuel, run diagnostics, and monitor live gauge data — all from your smartphone.

Tune your car, switch octane maps, upgrade packages, run diagnostics, and monitor live gauge data — all from your iPhone or Android. When upgrading tune suites, you pay only the difference in package cost with no extra fees.
The iE tune raises the rev limit to 7,200 RPM (stock pulleys) or 7,350 RPM (dual pulley), maximizing the supercharged powerband for a stronger, longer pull across the entire rev range.
Reducing the supercharger pulley diameter and/or increasing the crank pulley size spins the charger faster, generating more boost for substantial power gains. Single Pulley tunes require the 57.5mm press-fit SC pulley. Dual Pulley combines the 57.5mm SC pulley with a 188mm crank pulley — or use the single bolt-on 207mm overdrive crank pulley to go straight to dual pulley in one step. Do not combine the 57.5mm SC pulley with the 207mm crank pulley.
Build engine load and boost at the line using an advanced fuel-cut strategy for an aggressive, consistent launch. Cuts 0-60, 60-foot, and overall acceleration times.
Activate on demand by lifting off the throttle, downshifting, or free-revving. Adds an aggressive, head-turning exhaust note to complement the increased performance.
Use the cruise control stalk to run the radiator fans and coolant pump at full power, rapidly cooling supercharger and intake air temperatures to sustain peak power output.
A blend of 40% E85 ethanol and 60% 91 octane, E40 provides a cool-burning, knock-resistant, high-octane fuel that safely supports the highest power outputs available from the 3.0T platform. Requires an HPFP (high-pressure fuel pump) upgrade.
Use the POWERlink app and a few feet of 5/16" fuel hose to drain pump gas from the tank before switching to 100/104 octane or E40 ethanol for maximum performance.

Important: 2016–2018 A6 & A7 3.0T engines and some late-model ROW (non-US) S4/S5 use the CREC ECU variant, which is NOT compatible with this tune. See iE 3.0T CREC tunes for these vehicles. CREC engines are identified by a 4-bolt supercharger pulley (vs. the press-fit style on compatible engines).

We update our catalog daily to provide the most accurate fitment information possible. When shopping for parts, please use the “select your vehicle” car selector on the home page. Once you've selected your car, you can filter parts specific to it.
Additionally, on each product page, we have a tab for fitment information. By clicking on "Fitment", you can scroll and verify the part you are about to add to your cart indeed fits.
Furthermore, if you have a vehicle added to our vehicle selector and you are viewing a product page, you'll see fitment information below the "add to cart" button. If an item fits your car it will display "This Part Fits Your: Selected Vehicule". If an item does not fit your vehicle a message will display "This Part Does Not Fit".
A “Core Charge” is similar to the deposit you might pay for a can or bottle of soda. In many states, to promote recycling, you are charged a deposit when you purchase a can of soda and you receive your deposit back when you return the empty can. Many automotive parts have Core Charges that work the same way as a soda can deposit. The most common car parts that include a core charge are alternators, calipers, steering racks, and fuel injectors.
"MAP" pricing, or Minimum Advertised Pricing, means that the vendor set a minimum retail price that we're not allowed to violate. MAP items cannot be discounted because the decrease in price would violate that threshold.
