You already asked this question in another thread twenty minutes ago. You don't have to make multiple threads to get seen. Your question will be answered, but it might take more than 20 minutes..
Anyway, you shouldn't have to change your pilot or needle at all for this. The air screw should be at 1 1/2 turns unless the quad takes forever to come back down to idle after hitting the throttle. Then adjust accordingly.
As far as the jetting, I have a good but of work done to my blaster and I only have a 270 main jet. The only way to confirm your jetting is correct is to do plug chops.
Hopefully others chime in and give their .02 for you
