I'd be interested in this as well. I have the APR stage 1 and TCU. I love it and wondered if the 034 stage 1 would work well with the APR TSU as I do not see transmission software for the 8V on their site. IMO the transmission software is critical, totally changed the car and shifts as I would in sport mode. I am very satisfied with the APR solution but have other 034 parts installed and plan on using them for a rear ARB and some of their excellent quality mounts to stiffen things up.
