Bit of an update. I decided to purchase one of Racelogic's traction control kits for those wet days. A little bit of an impulse buy really, but I'm glad I did, all I can say is WOW!!!! It really does what it says on the tin. I'm very impressed with it. Calibration was a simple process of finding a straight piece of road with a 180° SLOW bend onto another straight. Took 5 minutes.
Now I can put my foot down and it grips in all gears.....very satisfying as the car launches off. I'm still playing with the settings as you can adjust minimum speed threshold, slip override for straights, launch settings etc.
There are 4 sequential cut sequences with increasing severities of fuel cut depending on the amount of slip detected. Very smooth and progressive.
Launch control sounds awesome with all the pops etc.
I can't wait for it to rain to see how it is in damp conditions.

Here are some fitting pics for those who like to see things in bits.

Finished injector cuts. Used plugs so I can revert to standard if required. Also sealed with silicone to stop water ingress (not pictured):
