more power please !!

Induction kit and exhaust with sport/race cats (ideally decat).  Will increase throttle response and power a wee bit.

But being naturally aspirated huge power gains are tough to come by.

I wouldn't mess with it too much, the 3 litre is a lovelly engine.

It's not the flywheel that is the problem.  What I really meant was that if you have an increase in torque from chipping an engine you can overload the automatic gearbox if the engine produces too much torque for the designed input torque (measured at the flywheel as opposed to wheel bhp) of the autobox.

My autobox is rated at 600 Nm input torque which is fine as my standard engine only produces 450 Nm of torque.  This is why I know the rolling road day on 15th March was a bit of a dud as according to Hypertechs rollers, my car is producing 610 Nm of torque at the flywheel, which would blow the gearbox!
