My rough numbers using Dinan's and BMW published HP and Torque numbers, I came up with around 366WHP and 421 wheel torque.....so the actual Dyno numbers of 364 and 410 aren't too far off.....although a bit more torque would always be welcome.
As Dinan states, each car is a bit different as are testing conditions.. Still the Stage 1 is a real kick in the pants for the car's performance IMO.
25 more lb ft of torque is very noticeable in a car, now double that. Wowser.
