Cars are complex machines these days, computers control much of the systems including the engine. Valve timing, fuel/air mixture, ignition and a host of other variables all contribute to the efficency and behavior of an engine. Cars from major manufacturers like Audi will come with a solid but conservative engine programming, to ensure long-term functioning. There are companies out there like STaSIS and APR that will modify engine programming to obtain extra power. In case of the TT-RS engine, there is a lot of room for improvement. The STaSIS engine reprogramming increases the torque output across the band up to about 420lb/ft and hp output is smoothed out and increased to about 380. The sweet spot is around 5000rpm where there is a 70hp & 70lb/ft of torque increase. The torque numbers are especially impressive. As a comparison, the new Porsche 911 Carrera S makes 400hp and 320lb/ft of torque.
The end result of all this is a smoother power delivery and a lot more torque across the board. Passing manoevers are now even more fun, when doing say 50km/h in 3rd gear, pressing the accelerator results in a neck-snapping surge of power and a dazzling buildup of speed. Fantastic stuff.
The drive itself was the classic Vancouver-Hope-Merritt-Lillooet-Whistler drive that covers some spectacular pieces of tarmac like hwy12 between Lytton and Lillooet and the Duffy Lake Road. I left early to get the Lower Mainland part of the drive out of the way and arrived in Meritt around 10am. A quick coffee and snack stop later I headed East towards Spences Bridge. This drive is familiar, I have done it before as part of a Boxster summer drive.
