I woul have to order the board and software and then find somewere in the UK that knows how neptune softwear works and knows how to tune by ITB.

I think i should find somewere that has tuned with ITB's first befor i order them. Which will be quite hard in the UK i think.

And i was thinking of getting a 4.7FD insead of the standard 4.4.
Are they worth changing?
