Have you drilled the air hole out any? Can't tell if yours is stock or not. I found that it made a big difference in performance for me - drilled mine to 1/16" and it kicks ..... You may want to go incrementally up to that size to find your desired draw etc. Btw, the coil placement looks spot on here.
No I haven't it's stock currently may look into that. I'll probably screw it up
