P0300 Code after Cosworth Cam install

So I have a P0300 misfire code and a Second O2 no activity code after a Blouch Turbo and Cosworth cam install. I have Stage 3 upgrades, NGR test pipe, with AEM intake.

I was reading through the Evo X service manual and it looks like they really stress looking at the camshaft position sensor.

So question:

1. So my tuner says its impossible to not have a P300 code after a cam install, is that true?

2. Anyone else have the P0300 misfire code after cam install?

3. I take it the second O2 sensor low activity code has nothing to do with the misfire? Thanks!

EDITED: I just realized I posted in wrong section lol.

Most aftermarket cams throw Misfire and most if not all tuners disable it.
