Awaiting the password for my tuneboy program (hopefully today) them im off to the dyno shop to get a figure on the Rs with Ti pipe with standard map, the 6105 race map and may try to make up a custom modified 6105 with the only dyno shop with the tuning link software in West OZ :\ . Johnno on your race RS do you have a custom / modified 6015 map?, I 'm keen on using yours if its okay but with the stock rpm limiter setting and maybe adding a extra 100 rpm for the idle settings, may lower the thermo fan settings too. Mainly trying to create a smooth power curve. Also I have a scottoiler, wheres the best place to access a vacuum line, if there isnt one I'm just going to fit a 3 way tap and run a permanent vacuum and incorparate a ball valve for manual on /off operation. Will post results of tuning and video of dyno run in the near future.
