An update at last!
Left the boost at 'safe' 1.8bar and it made 325bhp and 385ft/lb.
Not sure how accurate the dyno is.......car does go well though.
Weird thing is it seems to misfire in 3rd gear only? Researching on here and could be numerous things like plugs, leads, coil etc etc etc.
Proper map in January 2014 for fucking sure.......
It's this car
