Cutting out/studdering at 3k-4k

Wonder if it would attach if you Zipped it.

Dumb question, but what version of Link are you running? I ask because it sounds like it's only doing it under a little bit of load. You say it has no issue when you use light throttle, only when you give it a good bit of gas. Just wondering if you're using V3, and maybe something in your load tables got hosed up.
