Having not being able to solve this by setting up the car my only answer is that it is down to me being too heavy on the throttle and the additive not being cleaned off the tyres properly and it being a 2wd it inherently wants to spin or could it be something else that I have overlooked?

Have you checked the diff setting? Also, are all four tyres within 0.1mm diameter side to side?
"...additive not being cleaned off..." Does this only happen when you first put the car down to race? If you haven't dried the tyres well, then yes, it will veer off one way to another. In those circumstances it is usually because the front track is not perfectly in line with the rear track so the car tries to square itself up.
This is more prevalent with a link car if the links have any play in them at all. On my GT there is some play in the side links whatever I do unless I fit the O rings. I don't like the damping that way and prefer the side dampers, so the car does have a little shake of the hips every time it goes off the line.
Tyres must be completely dry before racing. Use an old towel and dry them off completely at least one heat before racing - one clear heat between drying and racing - so they are ready to race immediately. That's not always possible on club nights, so the first two or three laps need to be taken steady while the additive dries off and the tyres pick up any on the carpet to bed in to the track.
The diff should be tight with no slip whatsoever. If it slips that can also cause the car to veer off one way to the other.
If your suspension settings are right and the diff is tight, then try dying the tyres more. If that doesn't cure it then as you say, there is something you are missing. HTH
