Hi, I am new to my Caterham Roadsport 1600 sigma 150 HP. It seems to stutter slightly as you blip the throttle from idle, especially if the engine is slowing to idle (revs dropping). This is a pain when changing down as I tend to double de-clutch to rev match in the down changes. This means I have to give a huge bootful of throttle when on the brakes and there is a delay before the revs rise ready for the lower gear. Caterham says "they all do that" but I don't know - it seems odd to me.
Anyone with a Sigma 150 know anything about this or have any suggestions?
