A few years back I got my chip at Heinz Belgium but after that there were talks that some of their best moved out and created BR Performance. I've only heard good things about them so far from friends and customers that went there. Definitely going there for my next car now it's not a powerbox anymore! (3 or 4GC if I ever manage to decide between them
)
Edit: Maybe it'd be nice to add the country for each tuner? That alone may explain some price variations for us europeans
Oh and perhaps fuel savings in l/100km
I can help if you'd like although I've noticed many sites don't even mention it because most people rather use the extra power than the extra savings
