Turbo clutching and tuning

Hi guys
Have been testing my 12HCR
With boondocker turbokitt this weekend.
Everything works great. Except of a little tuning issues

Have been running 5psi @ 2000ft on stock head and timing key.
With AFR at 12 and 8150rpm

With afr at 12,5 i would get 8400rpm and "octn" in the display.

I can't turn up the boost beacuse of high rpm. Im now using the weights (80g) and spring boondocker delivered.

I am also using stock helix. But thinking of changing it out. Think its 42/40. Thinking of changing to 36-46

What helix should i go for?
Do you have other clutch recomendations?

I also have a little trouble tuning out lean spots with 1/4 throttle around 4300-6000. Try to give more fuel, but still get lean spots.

Is it normal to see 14-15 on cruising? I'm blipping the throttle to keep safe. But would love to be able to ride the trail with steady throttle.

I am a little disapointed in the throttle respons. Maybe it's beacuse i have tried to ad much fuel in midrange to tune out the leen spots, and/or helix

Day 1 it was real easey to start no mather what. Day 2 ( a little warmer) it was hard to start (had to give it som throttle), and sometimes stopped when i was on idle after a run.???

I have 3d tuning and only adding fuel on psi numbers.
