Jetta 1.8T (MK6.5) — Stage 2 Calibration

Up to 268 HP & 315 FT-LBS on 93 octane, with OEM-like refinement. Our strategy safely maximizes the factory turbocharger while keeping daily drivability intact.

Crackle (Overrun)

Lift-off character that adds a subtle edge with stock exhaust and turns up the attitude with downpipe/cat-back systems. Calibrated to keep it tasteful for street manners.

Refined Boost Control

Factory delivery can feel uneven during long pulls. Stage 2 smooths the curve for crisp, repeatable acceleration through the full powerband—OEM polish, enthusiast performance.

    The cable showed in the mail and he fit me in extremely quickly. After the tune it is a whole new car with a ton of power, and the sound is amazing!
