Hi

I installed the K4 turbo in my car some time ago. When I would step on the throttle it would adjust the timing I believe due to running to lean. I learned not to step on it for quite some time. Recently I installed larger fuel injectors with a new fuel pressure regulator. Now when I step on the throttle I'm getting misfire codes (which I was not getting before installing injectors/regulators). Since the misfire started after I installed the new injectors I'm not sure that I have bad coil packs. I'm curious if anyone has ideas on what I should check. I did install new NKS spark plugs. Do I need to gap them tighter/wider for running more boost?

Thanks!
