This dyno is of a stock RDX with Stage 1 and Stage 2 performance tunes.


Stage 1 operates in all 4 dynamic modes and delivers a 10 hp increase everywhere.

Stage 2 is configured for Stage 1 performance in snow and comfort and Stage 2 performance in Sport and Sport + modes. Stage 2 delivers 36 lb-ft more mid range torque and 28 more mid-range horsepower for a much more exciting drive. 

The dyno figures are lower than the Accord turbo due to our four wheel dyno reading 10% lower than our 2 wheel dyno, and the AWD drivetrain absorbing more power. This leads to about a 20% torque and power difference from the 18 Accord. The midrange percentage improvements (15%-19%) are similar.
