Just got done with my big project. It included a stage 2 LPFP, new stock turbos with upgraded wastegates from vargas, silicone inlets, upgraded outlet, high flow thing that leaves the turbo and BEF. It has a rough cold start which i believe is leaking injectors (1 and 3). Thanks for the quick reply.

Rough cold start could be HPFP or like you mentioned leaking injectors.
Let the car sit overnight & pull the plugs, if any are wet with fuel, those injectors will need to be replaced.
