Which one? Ultimately would like to have both in the future. Apr is having summer sale. I was going to get stage 1 and TCU tune while on sale tomorrow. Trying to find reviews of TCU tune but they aren't very plentiful.
My last car was a 12' S4 with stage 2 And pulley but it was 6 speed so I am unaware of the changes felt with the TCU tune. I was quite happy with the performance of the pulley
I have a B8.5 for reference. I do all my own work, so if I get the pulley I will have to then source a pulley remover and set aside time to install it etc. Plus no sale advantage on pulley right now.
