They use viezu maps for more info do a google search for viezu or chipped uk, wouldn't touch them with a barge pole, they diddle dyno results my 197 supposedly finished at 209 with their map, exhaust and k&n Apollo, car was actually running 181bhp!! and running very rich. One of the guys on megsport got conned by them as well, they gave him these great figures including how his boost pressure had been lifted, car was still running virtually standard....
Mulgari do some nice fabricating work on parts but as for mapping... ask the tuners on here about viezu and their maps
