QST ECU Software N55

Our QST ECU Software for the N55 Powerplant has been expertly developed on the dyno and tested vigorously on the road to provide a fully developed tuning solution offering exceptional gains in HP and Torque throughout the powerband and drivability exceeding expectations whilst still maintaining complete reliability as you would expect.

Stage 1:

-380- 385HP

-530NM

Stage 2:

-405-420HP

-550NM

For Stage 2 a de-cat or sports cat downpipe at the minimum, we strongly advise a intercooler too.

 Other features are available in our bespoke software, 'GTS' burbles, crackle on over-run and cold start delete.
