Our Sauce Management Device, or SMD is our new in-house tuning interface. With this device you can tune your MK8 GTI / R or Audi S3 8Y at the comfort of your own home just as dylan🫀 did.

Our initial release already includes MPI support and a fully customized boost control system, giving us complete support for upgraded turbo setups like the Vortex XL running full E85. And we’re only getting started.

For our current Cobb AccessPort customers nothing is changing. Our focus with the EQT SMD is exclusively centered on the MK8/8Y platform, and support for any additional platforms is still years away at best.

The SMD represents an exciting next step for the future of MK8/8Y tuning, while our commitment to our Cobb customers and ecosystem remains as strong as ever.

Available now for: VW MK8 GTI/R and Audi 8Y S3

Eight turbos. One WRX. Matched boost. EQT delivered.

EQT stood out in the AMS Performance eight-turbo shootout for the 2022+ Subaru WRX, with the EQT-660 and EQT-770 taking the top two spots for lowest backpressure and highest efficiency at every tested boost level. In this independent test the EQT-660 earned AMS’s recommendation for best balance, delivering full boost before 3,000 rpm, while the EQT-770 led peak horsepower at matched boost from 16 psi upward and reached 490 whp on E60 with boost climbing from 20 to 26 psi. Whether you want responsive street performance or room for a higher-powered build, EQT delivers results backed by testing.

🔥 EQT 660: AMS’s pick for more Best Balance: Full boost before 3,000 rpm, with the second-lowest backpressure and second-highest efficiency at every tested boost level.

🚀 EQT 770: AMS’s pick for more Headroom: Lowest backpressure and highest efficiency across all tested boost levels. Most peak power at matched boost from 16 psi up, reaching 490 whp on E60 at 20–26 psi.

Choose the EQT660 for responsive, balanced performance:
