Wouldn't think you would have to beg APR as they will supply you a map if you have pieced together your own K04 upgrade package.
Read towards the bottom of the page.
http://www.goapreu.com/products/turbo_trans20t_k04.htm"For users who have pieced the kit together on their own, software is now available separately from the kit. The software requires the OEM S3 K04 Turbocharger, OEM S3 Injectors, APR High Pressure Fuel Pump and Full APR Exhaust. Customers with existing 2.0T APR software may purchase software at a discounted price."
I know its a different turbo, but if they will do it for one, they should do it for others.
