180sx starting problem

Having a problem with my 180sx when it's starting.

Car is sr20det with t28 turbo, 550 injectors, z32 afm and mapped on nistune.

Car won't start from cold unless I try a few small turns of the key and then hold foot to floor, after spluttering a few times it will rev freely and once the engine has run for a minute it will start up first turn of the key.

Checked compression and all were above 140, checked timing and it's perfect. Really stumped, anyone any ideas??
