all i asked is who does them so i can look at what spec each is and then come to a semi informed conclusion for there.....

but like i said all i have seen for black top is the kent ones so far....

anyways alot of tuners can ask firms to do a special profile grind for one off applications and this is what most of the secret spec refers to in many cases as tuners are oftern gaurded about giving information so that other people can not simply ring up a firm and ask for "the profile you did for joe blogs last week please" instead of going through the company that commisioned the grind.
