Cylinder misfires

So I just got my cobb today and my first pull I get the SES light and no power along with a rough acceleration. I pulled the codes and it's misfires in 3 cylinders. The spark plugs and fuel injectors were replaced 10k miles ago. I just bought some new coils, should that do it?

Also a possibility is a walnut blasting. Were the injectors coded? Also oem plugs? Coils are an easy cheap remedy. I had to replace all plugs, coils, injectors and get a walnut blasting to remedy my Cobb misfires. This was over a few months as I went to Stage 2+ with ProTune.

Not sure I have the service records. I just got the car a few months ago. Car ran awesome until the first time I pushed it with cobb. And yeah everything OEM since it was done at bmw
