I went down to JBS with my logs and had a chat with Mike and Kev. In the end Kev re-flashed my ECU and we went for a quick spin up the by-pass, I could tell immediately that there was a vast improvement. According to my boost gauge (and it's only a Halford's Auto-Gauge jobbie btw) I'm spiking at 23-24psi and then holding at an easy 20-21psi every time, before there was no spike at all and I was only reaching around 18psi. My original map is over 18 months old and C-C have added a tweek or two since then so all good. Until I started using Vag-Com I was perfectly happy with the car and it's performance and it's only curiosity that made me search a bit further, there is now such an improvement that driving the car now is giving me the sort of grin I had when I was first re-mapped. Big thanks and a top job JBS.
