Okay, there is a possibility that I might be upgrading to a new Audi A4. The issue is that I have a APR Stage 3 turbo and would like to keep using it. However, APR has stated that there is no support for 2002+ for the Stage 3 kits and that there probably will not be any... they will be working on a Stage 3+ kit instead. What would be recommended for ECU programming that might be compatible with the APR Stage 3 hardware and injectors and make it work on a new 2005 Audi A4? Thanks, David

This would have been for a B6 version A4... I was hoping to not have to spend more money on the Stage 3+ since I think a Stage 3 is plenty of power... ;) Besides, they are not even sure when the Stage 3+ kit will be ready. David
