Need a dyno! Always was skeptical with their advertised numbers - very aggressive compared to the competition.Reported HP/TQ:
425hp; 460ft-tq (on 91 octane)
None! Never a check engine light, even under hard acceleration and spirited driving. No inconsistent throttle response or weird noises. So far the tune has been great and I use this as a daily too.
Average Daily Fuel economy:
Stock 7L/100km (~34mpg)
Stage 2 9L/100km (~26mpg)
I also think the average daily would go down...especially with a Stage 2, as it is WAY too much to hit the gas and go!
