Hi I have read loads of info on tuning boxes for my 2.0dti veccie c (2003), what i need is a couple of testimonials off people who have them, what would be great is if you could tell me what you got, if it really works and where you got it from???? Oh and how easy it is to fit.... I know its a lot to ask and maybe a bit lazy of me but i am slightly blinded by all the info, i need real performance increase oh and of course for the best price!!
