Went on till around 5pm with the last car an M3 running 344bhp.
Thank you to everyone how helped and turned up to day, the good heart of the vag owners community managed to raise £802 for cancer research :-)
The highlight of the day for me was having a beer at 6pm after 9 hour non stop on the dyno, just kidding the R32 turbo which munched at my dyno with 445bhp gave be a buzz, and my car having it's first power run with the full combination of tuning mods working together punching out a huge 346bhp, at what could have been over 430lbft but only to be limited by the oem clutch slipping at 2300rpm at 290lbft..
Thank again to everyone
