What are you talking about? Unlimited VINs? Hacked?
DHP used to charge per VIN but when the company went away (Charles) the owner opened it up to unlimited VINs. There is no reason to have a "hacked" version of DHP and I can't imagine that the older versions and database will have all the same mapping that the newest version does.
If you already have a tuner all you need to do is log in to register on the DHP website with your DHP number and download the software.
