Leawood911:
Correct - slighly lower redline would 'detune'.  That is what I was thinking.  Perhaps a different ECU for more street driveablity.  It is exactly because the GTS price and the GT3 price are so close already that it makes sense to sell it with a version of the GT3 engine other wise, without the GT3 based engine it would be a complete no brainer to get the GT3.

The ECU in the GT3 already maximized that engine for drivability in the lower revs.  To improve things further, you could change the camshafts perhaps to lower the torque peak rpms.  The problem with lowering the redline to make the car respond better at low revs is that you also have to raise the gearing with the lower redline and then you give back virtually any gains you made by lowering the redline and retuning.
