rica is a company based in Wateringen in Holland, they now have a second firm in Waalwijk. For a friend of mine (stock 172) said that they did some good work, well he let install the chip (costs € 455). Nothing wrong you would say. Well after one week did a dyno, cause car felt to have less power. Result not even 160 Bhp. Called the owner (Roel) and he multiple times sayd yes I will call ya bla bla story. So I would NOT recommend RICA engineering.
This weekend at the races I will speak to the guy and see what he has to say. will let youse know if this firm is reliable !!
cheers
