Hi I have a 2001.5 s4 b5 tiptronic with k04s , car was tuned by a known Audi tuner but my table for desired pedal position was left all
Stock and so was desired afr left stock (14.7)

The issue is  I raised the deisired pedal from 0.5, 0.10,0.20 to 10%, 20%, 30% etc etc and changed desired afr in the last two tables from 14.7 to 12.5 but now when I go full throttle and if I hit 5500 or higher the trans feels like it slips and The converter won't lock up. If I clear the ecm it's fine the converter locks back up. What do I need to do? What is the alternative to enriching fuel in the upper Rpms under full throttle?
