You can make your car "quicker" with trans tuning alone--I've seen up to 4 tenths in the 1/4 mile !!
Deleting TQ management gets rid of the TQ deducts during shifts which can be as much as 30% !!
The best mod period for any A4 car is a stall converter--engine or trans---
Another 4-5 tenths more are common in the 1/4 mile---( say around a 2800-3000 stall)--If you are unfamiliar on how a stall works here is a brief description---Say when completely stopped you floor it--The RPM's will spike up to around 1400 immediately (stock stall) At 1400 your RWHP is maybe 100----So your engine has to start pulling with only 100 RWHP--
BUT if your stall is a 3000--- then when you floor it the RPM's spike to 3000 immediately where now your engine may be making 250 RWHP !!!! and starts pulling from there---Makes your car a beast down low---Without even touching your engine---
