a4 ws6 99 won't crack second somethin wrong????
A tuner will also work but less reliably. Trannys have variation and some may not be able to be tuned with a handheld to make them chirp. There are many concerns with the changes the tuner making not being the best for the tranny.
You can study up to make your own decision or take the recommended route with a shift kit.
