Could it be the plug leads--how old are they?

Can you avoid it by using light throttle?
As in is there a certain amount of throttle over which it gets crap
Thats what my other car did when the plugs were flowered

Well, it should not have much torque under about 3k, but its the variation/stuttering of torque that suggests issues.
If it turns out not to be a fault, a supercharger should help!!

what do u mean by original ones?
Original one that came with the car 5 years ago?
I would just change them + plugs, I felt a night and day difference with new ones in.

Happens from 30% throttle or higher.
I checked the leads and they seem to be the original ones.
That sounds EXACTLY like the issue i had with bad leads and plugs, get some good quality plugs and leads, even if it doesn't fix it, its still a good thing to replace
