interesting link to the Litchfield site from JohnV6, in that it also ties in with the Alpine thread.

Quote from the Litchfield Alpine upgrade page :-

Our revised Stage 1 upgrade lifts power significantly to 310PS / 305bhp (+56bhp) and 306lbft/415Nm (+70lbft) without sacrificing the driveability and smooth power delivery of the engine. The new gearbox calibration refines the Launch control strategy to suit the new power along with improvements in shift response and torque control.
