We’ve redesigned the N51/N52 tune from the ground up. Adjustments to Vanos, Valvetronic systems allow for more toque for the street. Adjustments to fueling and ignition timing help the car make big power up top, pulling the car faster to its new redline of 7200rpm (Manual Trans or Auto if you have a xhp tune).
Stage 1 +12 – 17 Horsepower (For stock or lite modified engines)
Stage 2 +15 – 22 Horsepower (Off road use / Exhaust modifications)
We also offer options for Lifter mod adjustments, Burble (pop and bangs) and intake swap (3 Stage Manifold)
