What It Is
A complete hardware and tuning package for the BRM engine in the 2005.5-2006 Jetta, built for the 5-speed manual. It's designed to push output past 150 hp, roughly 57% over stock, using a proven combination of parts rather than a piecemeal build.
What's Included
Why the Tuning Is Different
Kerma calibrates this tune individually for each customer's specific parts combination rather than offering generic staged tunes. The goal is tighter boost control than a typical aftermarket tune, aimed at better drivability, turbo lifespan, and reliability from the first drive, along with more usable torque, less smoke, and lower exhaust gas temperatures. Free tuning updates are included if you add parts down the road.
Installation
Kerma works with both authorized installers and DIY builders, offering free tech support and how-to guides. Call ahead to plan your install, or work with a TDI-savvy technician.
Common Questions
Which clutch option should I pick?
The Stage 2 Daily Clutch suits most drivers. The Stage 2 Endurance Clutch is the better choice if you're planning an injector upgrade down the road.
Do I need a custom tune from a third party after installing this kit?
No. The tune is included and calibrated specifically for this parts combination. Kerma also provides free tuning updates if you add more equipment later.
Will this fit the DSG automatic Jetta?
No, this specific kit is built for the 5-speed manual. Kerma offers a separate version of this kit for the BRM engine with the DSG automatic.
What years and models does this fit?
2005.5-2006 Volkswagen Jetta with the BRM engine.
