Sticky FPR maybe or weak HP pump.
I'd swap out the FPR first... The correction values won't be honed in when started from cold, it's monitoring crank acceleration per piston stroke, when you have even remotely dicky injectors these figures will be thrown around a lot - they come in when warm and it really starts to use them properly.
EDC15 isn't the best at correcting the values, they're a bit slow and the calibration isn't amazing - that's why you hear HDis hunt a little when you first start them, they don't run instantly smoothly, it's because of it trying to adjust the injectors, but as they wear, the calibration for this just isn't great, so they hunt a little.
Give the leakoffs a try, but remember that the HP pump is capable of injecting probably 35mm^3/str at idle rpms, at idle you're asking for naff all, the leakoffs wouldn't cause enough leak at idle to stop it starting.
