Problem
When under gentle accelleration, the car judders and holds back, could this be a dis pack problem or just atmospheric differences causing the ecu to hold back? It is normal when on boost fully that is why I ask. PLEASE help as I'm getting very concerned

could be the coil packs. Personally I would check your spark plugs and maybe change them depending on when they were last done. Also check the gaps on the plugs should be around 0.7mm
Whilst they are out, check the coil packs themselves to see if they have broken down. There is a rubber cap type thing on the end of the coil pack, gently remove this and you should be able to see if they have cracked which can cause the spark to break down.
It could also be a bad batch of fuel or running to low an octane, but I would go with checking the plugs first
If the car drives okay on full boost// full throttle then I would say it is more likely to be the plugs and not the coil packs.
Also just noticed you have an induction kit, it may be wise to remove it and gently clean the maf sensor to get rid of the muck that will be on there. Be very careful though when doing this.

I clean my maf (my92 with apexi induction kit) with a dry lint free cloth, but you must be gentle in doing this. (some people use brake cleaner)
It could also be a fuelling issue. On light throttle if it is overfuelling then it could cause fouling on the plugs and thus causing hesitation, when on full throttle the plugs clean up and so everything appears normal
