Light Throttle Hesitation

Hi. I'm having some issues with slight hesitation issues at very very low throttle. The car pulls fine and boosts fine with no codes when more throttle is applied. I mean really light throttle, just maintaining speed in traffic so your foot is barely moving the pedal.

I installed new genuine bmw plugs under 1k miles ago. Other than that, I had an injector go bad a few hundred miles ago. I only changed the one, my originals were index 7 I think and this was index 9, from what I read mixing early injectors should be ok.

Failing that, I'm thinking it may be worth replacing the coil packs. I'd like to do all 6 injectors and get a walnut blast as well but would like to target my money first on whatever is the most likely cause of this hesitation.

Any advice appreciated- I did try and search before posting but with no success.

Mods as follows- MHD Stage2+ 98 - Wagner Evo 1 Performance I/C - VRSF Intakes - STC dp's - BMWP Y-Pipe
