I`ve added around 5.75 deg with lemmiwinks,but that was with a fair bit of logging and letting it adapt after each adjustment. But as phil says water/meth is next on the list and then should be able to add quite abit more.
I think you could proberly get abit more if you wanted jay, Crank the WG abit to bring the duty down and maybe add some timing via lemmiwinks if its possible with your map. Might be worth a PM to will to see if it is possible although from logs ive seen from p torque maps timing pull is already quite high.
That was a good blast down that bypass Dan, i though you were just saving on petrol. My mate with the C2 couldnt belive how quick i passed you lot.
