2015 - 2017 Volkswagen MK7 GTI 2.0t Stage 1
BDT Stage 1 ECU Tune
2015–2021 Volkswagen Golf GTI MK7 / MK7.5 (MQB • EA888 Gen 3 • IS20 • FWD)
Your MK7 GTI is already a weapon — but the factory file keeps the IS20 on a short leash. BDT Stage 1 sharpens throttle response, hits harder in the mid-range, and carries clean power to redline while keeping daily drivability and safety logic front and center.

Power Gains
Expected Stage 1 gains on 93 octane: up to 268 WHP / 307 WTQ (approx. 308 HP / 353 TQ at the crank).
| Stage | Horsepower | Torque |
|---|---|---|
| Stock Advertised numbers | 210 HP | 258 TQ |
| Stock BDT dyno numbers | 263 WHP | 280 WTQ |
| Stage 1 (wheel) | 268 WHP | 307 WTQ |

Quick view:
- Required: None (stock hardware supported)
- Recommended: Intake, upgraded intercooler, drivetrain insert upgrades
- Highly recommended: BDT TCU tune (especially DSG)
Upgrade matrix:
| Part / Upgrade | Required | Recommended |
|---|---|---|
| Air Intake | — | YES |

| Downpipe | — | Not required (Stage 2+) |
Frequently Asked Questions
Q: Is Stage 1 safe on a stock MK7 GTI?
A: Yes — Stage 1 is designed for factory turbo/hardware with OEM-style safeguards and torque modeling.
Q: Do I need a TCU tune for DSG?
A: You don’t need it to flash Stage 1, but it’s highly recommended to improve clutch pressure, shift logic, and torque handling.
Q: What fuel do I need?
A: 91/93 octane supported depending on your file. We set the calibration up for your fuel quality and climate.
Q: How do I flash?
A: You’ll flash through the OBDII port using a Windows laptop and the BDT Remote Flashing Suite.
Q: Can you disable crackles / tailor map switching?
A: Yes. We can enable/disable features per-map and tailor behavior to your goals while keeping safety limits in place.
