I don't like that statement to be honest. In the meantime I have jetted two 300's (a 2018 and a 2019-which is mine) using the NECW and they both run well. The NECW is pretty much in the mid range between lean and rich, the NECJ is on the leaner side. The NEDW is half a clip richer than the NECW and goes towards the richer side. And so does the NECH....
