Try before you Buy

I apologise if this is somewhat cheeky, but does Rennzport offer a trial period for the JB4? It might be good for business especially for those customers that are a bit unsure. I see other tuning houses do this.

I for one would be happy to pay a non-refundable install and logging fee for a weekend trial as well as a refundable deposit. If I am happy that the tune meets my expectations then I will purchase it. It will also assist the customer in learning how to install and remove themselves which to me sounds daunting.
