RX1 turbo help

[proplant21]

I have a Rx1 motor in a Rzr 900. It has a A and S Racing conversion. My research shows that it's a rear mount setup. This thing has been a basket case but I've have figured out most of it. No boost leaks, billet T's and cap. Pilot-20 Main 135 Power jet-75 Air screw 2 turns out Green springs needle clip raised one clip. All my A/F are good. Little lean at idle 14, but with a little throttle goes immediately down to 11. From low end to high slowly increasing the number goes from 10.5 to 12. My problem is when I go WOT the AF goes to 13-15 and sputters until it catches itself and then it takes off great. Any help would be great Thanks

Probably would get more help with your question on TY 4 Stroke.
