Fitment & Compatibility

Unlock the Full Potential of Your Audi TT (8S)

Exclusively Tuned by Boost Dynamic Tuning — Built by Enthusiasts, for Enthusiasts

If you own a TT, you didn’t buy it to be “pretty quick.” You bought it for that perfect mix of style, balance, and speed — and you know there’s more hiding under the hood. At Boost Dynamic Tuning, we don’t do generic flashes. We write in-house Stage 1 calibrations that bring your EA888 Gen 3 to life with real data, real testing, and a feel you’ll notice instantly.

With 11+ years of hands-on tuning experience, dyno-verified development, and street/track validation, our Stage 1 ECU Tune turns your daily TT into a confident backroad weapon — smooth when you want it, savage when you don’t. No gimmicks. No mystery additives. Just fast, reliable, repeatable performance.

Crackle Pops — The Overrun You’ve Been Waiting For

This calibration feature (also known as overrun) adds real auditory character to your TT. On decel from higher RPM or quick revs in Neutral/Park, you’ll hear sharp crackle pops through your exhaust/downpipe (best heard with an aftermarket system). It’s the perfect extra spice for drivers who want aggressive sound without a rough daily tune.

• Controlled & safe implementation
• Active only in Dynamic/Sport Mode
• More pronounced with aftermarket exhausts
• Automatic safety reduction if EGT climbs too high

⚙️ Boost Control Refined

From factory, boost delivery can feel bumpy and conservative, especially during long pulls through the powerband. BDT reworks the boost model to deliver:

• Smoother, more linear boost ramp
• Instant throttle engagement
• Consistent power through every gear

This isn’t just tuning — it’s precision-built calibration that transforms the way your TT drives.

Built for the Streets. Proven on the Dyno.

Stage 1 methodically increases performance to safely max out the IS20’s potential while keeping daily drivability intact. The result is a TT that feels lighter, sharper, and way more eager everywhere in the RPM range.

Don’t just drive your TT — make it yours.
