Hello I am relatively new to the forum and the tuning world. I have a small fleet of VW TDIs that I take car of. I have been reading a lot on how to tune them and hope to add some of my modified files to them at some point. I have a little ways to go but I hope I can use the information from this site to help me get where I need to get.

Does anyone have anyone have any suggestions what direction to head for ALH Tuning? I have VAG suite and worked with some of the maps but I am confused with a couple.
