Black smoke is just the name of the company. You buy a galleto lead (£25) then buy the file from a guy called andy who runs the blacksmoke site (top bloke, very helpful and will give you his phone number if you get stuck but its pretty simples) for £45 and your away. So far my tdi 110 non pd has this map, pd130 turbo, .216injectors, custom charge pipes, fr&r large bore downpipe and decat, turborevs sidemount intercooler and it flies. Egr removal is good but it can make the engine managment light come on with pre2001 (i think) cars
