Give me your thoughts on this guys. My R33 GTR (Non V-Spec) is doing about 360 BHP. (400+ on it's way!). More than quarter throttle in any gear gets the front torque meter reading to about 10, at any speed. Is this the first sign of the clutch going, or because I have one new and one older rear tyre? (3mm difference in tread depth.) Is the wheel sensor accurate enough to pick than up as what it thinks to be wheelspin? Any ideas?
