Okay, I'll break it down. Find someones tune for the same year car as yours(check HP's repository on there site) Take that tune. Change the Vin to match your cars vin on the tune, Go to your car plug in the tuner and do a full rewrite, It will then make you use the credits at that piont. Since its your vin and matching OSID it will be fine. Change the tune as needed. You could even save the ZZP tune or what ever you currently have and paste over the table to the new found tune after you have done the first flash
