Lt4 supercharger part throttle pinging - Page 2

I’m on my second tuner first one had super choppy idle on cold starts. Second guy nailed it. My only concern at this point is this part throttle lean issue. Yours sounds like a tune issue as well to me.

Can anyone tell me at what % on the throttle they have their PE set to come on? I’m not getting anywhere trying to get rid of the part throttle pinging. At higher speeds and easing into the throttle I’m still getting KR up to 7-8 as the boost comes in. It’s not going into PE mode. When I look at the tune file it has PE set to come on at 30% throttle. I’m at like 18-20% throttle when this happens. Can I just lower that threshold down to around 15 without problems?
