2018 - 2025 Audi SQ5 3.0t Stage 2

What is our tune all about you ask?

Slide behind the wheel, tap the start button, and feel the rumble — this isn’t your stock SQ5 anymore. With our Stage 2 tune, every green light becomes an excuse to grin. Power delivery is instant, torque hits like a sledgehammer, and that V6 comes alive in a way Audi should’ve built it from day one. You roll onto the throttle and the car pulls — effortlessly, aggressively, addictively. Whether you’re carving up backroads, flying down the freeway, or just flexing on a casual night cruise, this tune transforms your luxury sedan into a sleeper missile. It’s smooth when you want it, savage when you don’t — the perfect balance of class and chaos.

SQ5 3.0T ECU TUNE+ TCU

From the factory, the Audi SQ5 3.0T put down a solid 280WHP and 370 lb-ft of torque — smooth, capable, and refined. But with our Stage 2 ECU tune, we crank things up to 390WHP and 510WTQ That’s a massive +110 HP and +140 lb-ft gain, unlocking the full potential of the turbocharged V6. Throttle response is sharper, midrange pull is stronger, and the car finally feels as fast as it looks — all while retaining factory reliability and daily driving comfort.

CRACKLE POPS — BECAUSE QUIET CARS DON’T GET NOTICED

You lift off the gas and BOOM—your exhaust starts talkin’. That glorious crack-pop-pop-pop isn’t just noise—it’s overrun magic, dialed in with precision to give your ride the drama it deserves. Whether you're ripping through tunnels or revving at a meet, the tune delivers a symphony of controlled chaos every time you let off the throttle.

We offer three crackle levels to match your vibe:

• Low – Subtle, refined, perfect for daily drives and sneaky pulls

• Medium – Noticeable and fun, turns heads without waking the whole neighborhood

• High/Intense – Loud, aggressive, and borderline ridiculous (in the best way possible)

Even on a stock exhaust, you’ll hear the difference. But with an aftermarket setup? It's absolute madness. Get ready to light up the night with every lift — because the streets weren’t made for silence.
