BDT Stage 2 ECU Tune — 2015–2021 Volkswagen Golf GTI MK7 (EA888 Gen 3)

If you own a MK7 GTI, you're sitting on serious untapped potential — and we know exactly how to extract every ounce of it. Boost Dynamic Tuning’s Stage 2 ECU calibration delivers a sharper throttle hit, a harder mid-range, and clean power that doesn’t fall off up top. This is a daily-friendly tune built with track-tested logic and real-world refinement.

Why Boost Dynamic Tuning?

BDT doesn’t sell hype — we publish proof. Every stage is written in-house, validated by live before/after dyno runs, and refined through 11+ years of hands-on VW/Audi MQB tuning. No resellers, no copy/paste files, no mystery additives — just calibrated power and consistent drivability.
