Philadelphia's Classiest Drunkards
I used this.

But see my car was leak tested and fixed(inj/tb seals and LICP) at CBRD 3 week before track and then 2 days before track it was tested again and strapped on dyno for tune. So that leaves me to think that only when shifting and engine rocking is/was the issue as well as the wrong LICP fitment.
