Sven, thanks for the inquiry!
We truly appreciate your kind words regarding the Project ST cars. For some reason, praise from a German always resonates more deeply with us Americans
Regarding the TrackSTer's additional output, this was achieved in conjunction with Mountune. We went to them with specific criteria for this build (horsepower, torque curve, RPM band, etc.) and they chose the hardware and ECU calibration. This is all still in the developmental stage (still tuning our management for use with crappy California low-octane fuel), but from what I understand Mountune will soon offer everything from the TrackSTer engine build.
Send an email to David Moore and let him know you spoke to me about this. I'm sure he'll fill you in on what their plans are likely to be.
Of course, if you have any more questions feel free to contact us again!
Cheers,
