UNLEASH YOUR 3.0T

Your S4, S5, or SQ5 isn't slow. Audi's factory programming is holding it back. iE tuning reprograms the engine computer from your phone and turns the B9 3.0T loose, with up to 505 HP on the stock turbo and up to 739 HP with a hybrid turbo. Savage when you floor it. Civil when you don't.

UNLEASH YOUR 3.0T

GAIN UP TO 739 HP

Stage 3 is purpose-built for bolt-in TTE810 and Pure750 hybrid turbos. iE's world-record-holding calibration delivers supercar power with sharp transient response, minimal lag, and a pull that keeps going to redline. 591 HP on 93 octane with stock fueling. Up to 739 HP and 710 ft-lbs on Stage 3+ with E70.

GAIN UP TO 739 HP

FAST, NOT RECKLESS

Even the best tune can't control bad fuel or a failing part. iE AutoProtect is your last line of defense. If trouble shows up, it lowers boost and power to keep the engine safe, then restores full power when conditions return to normal. A unique code is logged so we can help pinpoint the problem. Included on all stages.

FAST, NOT RECKLESS

NEVER WAIT ON BOOST

Anti-lag launch control builds turbo boost before you leave the line for an aggressive launch that cuts acceleration times. Adjust your launch point in real time to match tires, surface, and conditions, with no reflash. For roll racing, rolling anti-lag holds a set RPM and speed while building boost, then unleashes it the instant you want it.

NEVER WAIT ON BOOST

SOUND FASTER TOO

The factory overrun is so mild you can barely hear it. Stage 2 and Stage 3 files turn it up, with a more aggressive crackle in Dynamic mode and crackles on free revs in park or neutral. Your car won't just be faster. It will sound it.

SOUND FASTER TOO

TRUEFLEX: E85 MADE EASY

Ethanol is rocket fuel for your daily driver. It carries more oxygen, burns cooler, and resists knock, which means more power than pump gas for far less than race fuel. The TrueFlex flex fuel kit lets the factory engine computer read and instantly adapt to any ethanol blend. Ethanol options are available on all stages.

TRUEFLEX: E85 MADE EASY

MORE FUEL. MORE TORQUE.

Stage 1 Plus and Stage 2 Plus files are included with your tune and built for the iE High-Pressure Fuel Pump upgrade. The extra fuel delivery unlocks the full potential of E85, good for 505 HP and 650 ft-lbs of torque. Requires the iE HPFP upgrade.

MORE FUEL. MORE TORQUE.

SHIFT LIKE YOU MEAN IT

iE engine tunes make more torque than the stock transmission programming allows. A Stage 1 TCU file that raises those torque limits is included free with Stage 1 and Stage 2. Want the full transformation? Add the iE Transmission Tune for launch control in every mode, lightning-fast shifts, and shift points optimized for acceleration. Stage 3 requires the matching transmission tune, and the Stage 3 TCU file is a free upgrade if you already own it.

BUILD GUIDE

Your path from stock to the ultimate S4, S5, or SQ5
1

STAGE 1: START HERE

A flash-only upgrade for a completely stock car. Up to 505 HP on E85 with nothing more than the tune, and it adapts to take full advantage of an intake, turbo inlet, and intercooler when you add them. Includes the Stage 1 TCU file, a 6500 RPM neutral and park rev limit, speed limiter removal, and brake boost.
NO HARDWARE REQUIRED
2

STAGE 2: FOR THE EXHAUST LOVER

The B9 3.0T's factory downpipe is large and efficient, so Stage 2 does not add power over Stage 1 on the stock turbo. What it adds is the calibration your aftermarket downpipe needs, plus a more aggressive overrun and crackle in Dynamic mode and crackles on free revs in park or neutral.
REQUIRES DOWNPIPE
3

STAGE 3: HYBRID TURBO

Pump gas power on stock fueling. Add a bolt-in TTE810 or Pure750 hybrid turbo, an upgraded intake, turbo inlet with hybrid adapter, and intercooler for up to 591 HP on 93 octane. Stock downpipe files are included. Requires the matching transmission tune.
REQUIRES HYBRID TURBO
4

STAGE 3+: GO ALL OUT

Everything in Stage 3 plus an HPFP upgrade, 4 bar MAP sensors, and upgraded injectors. Unlocks E70 and TrueFlex for up to 739 HP and 710 ft-lbs with an iE downpipe, or up to 667 HP on the stock downpipe.
REQUIRES FUELING UPGRADES

img FITMENT NOTES

Requires a V4 POWERlink. Older V3 tuners cannot flash the B9 3.0T.

2021-2024 B9.5 transmission tuning has limited support. Some transmissions have security locks that cannot be unlocked. Follow the Audi B9.5 TCU Unlock Guide before buying a transmission tune for these years.

Downpipe notice: aftermarket downpipes used with Stage 2 and Stage 3 are motorsport products. They are not designed to meet emissions standards, are not CARB compliant, and are not for sale or use in California or anywhere prohibited by law.

FAQs

How do I install the tune?

Plug the POWERlink into your OBD2 port, open the app on your Apple or Android phone, and follow the steps. The flash takes minutes.

How much power does it add?

Stock, our dyno shows 346 HP. Stage 1 makes 427 HP on 91 octane, 446 HP on 93, and 505 HP on E85. Stage 3+ makes up to 739 HP with a hybrid turbo. Dyno numbers are for reference against stock only. Your results will vary with fuel quality, local conditions, dyno brand, and correction factors.

Do I need a transmission tune?

Not for Stage 1 or Stage 2. A Stage 1 TCU file that raises the transmission torque limits is included at no cost. The full iE Transmission Tune is optional and highly recommended. Stage 3 requires the matching transmission tune.

Does Stage 2 make more power than Stage 1?

No. The factory downpipe on the B9 3.0T does not restrict the stock turbo, so power is the same. Stage 2 adds the calibration needed to run an aftermarket downpipe, plus a more aggressive exhaust overrun.

What do I need for Stage 3?

A TTE810 or Pure750 hybrid turbo, an upgraded intake, turbo inlet with hybrid adapter, intercooler, and the matching transmission tune. Stage 3+ adds an HPFP upgrade, 4 bar MAP sensors, and upgraded injectors. See the Stage 3 guide for the full list.

Can I run E85?

Yes. Ethanol options are available on all stages. TrueFlex adapts automatically to any blend and requires TrueFlex hardware. On hybrid turbo cars, TrueFlex requires Stage 3+. More on TrueFlex.

Is it safe for a daily driver?

Yes. iE AutoProtect is included on every stage. If it detects a problem it lowers boost and power to protect the engine, then restores power when conditions return to normal. More on AutoProtect.

Will my existing POWERlink work?

Only if it is a V4. The B9 3.0T uses updated flashing protocols that older V3 POWERlinks cannot handle. Check that the serial number on the back starts with V4.

What does it cost to upgrade stages later?

Only the price difference between the two stages, with no extra fees. Install the matching hardware, then buy the upgrade in the POWERlink app.

Are tune updates free?

Yes. Your purchase includes free updates to tune revisions, new octanes, standard features, and software updates. If Audi issues an ECU update, that is included at no charge too.

Can I use my POWERlink on another car?

Yes, on up to 5 different VINs. Tunes are sold separately for each car.

Can I move the tune to a different car?

No. Once applied, the tune is permanently registered to that vehicle. It can transfer to a new owner along with the car.

My car is a 2021 or newer. Can the transmission be tuned?

Possibly. 2021-2024 B9.5 cars have limited support because some transmissions have security locks that cannot be unlocked. Follow the Audi B9.5 TCU Unlock Guide in your POWERlink app before buying a transmission tune.
