If DMC reccomends 300's my plugs were white with those settings. I have the exact same mods only aliens and bumped it up to 320 and it should seem good on the top end. As for the pilots IMO 30 pilots dont seem to have such a big effect idling and starting off. And for the needle if it really doesnt have any mid range then you should lower it one clip so its a little richer and go from there.
