Wasn't going to write one up here due to clogging up the board with more AKS thank you posts, but I had to. Alex fitted new LSD and new engine I supplied. All went a lot smoother than I thought (well it did for me as I was at home with my feet up)
Picked the car up Saturday and its absolutely transformed it. Was running AXX at stage 2+ now running ED30 BYD what is stage 3 for a GTi. It's running fantastic and I now know what all the KO4 fuss is about
Many thanks Alex.
