That's fine if they don't want to "put their name on a limited tune." However, it will be not the only product it will work on. All it is is an add-on to a full program. No, it will not make sense to buy HPT just to tune this one particular vehicle, but they need to give there customers, especially the ones that own shops, the ability to tune the most popular cars.
Now Bill told me, "My mother drove a V6 Camaro, and didn't tune it." This was a pretty dick comment to make to a paying customer, but I guess that's he does business. But, you look around online and people are modding these cars almost as much as the V8 guys. Even basic tuning ability would be nice without having to buy an entirely new program.
