So i've got a s5 turbo running a powerfc with 4x720cc injectors, good compression starts fine cold but when its hot i'm having to run something like 18ms cranking injection to get it to even want to start but still struggling quite a bit, i've checked various threads that all cover low compression and turning the fuel down but my issue seems to be the opposite?

Just using the standard powerfc timing maps and i've road tuned the fuel myself, drives spot on its just the starting is the issue and a rich idle which i've boiled down to old style big primaries.
