Phil your a businessman, surely publicly slagging off you competitors is not a good thing? unless you are after a law suit.
It appears that its only the customers of the tuners that do this!
As chip said healthy competition is only a good thing, however i dont think it is really the way to gain a good rep.
Jamsport are a prime example, never see there punters on here slagging off other rst tuners, only praising them for there work, I think this will carry them a lot further than having the fastest car etc.
